The MSP34x1G
family of single-chip Multistandard Sound Processors covers the sound
processing of all analog TV-Standards worldwide, as well as the NICAM digital
sound standards. The full TV sound processing, starting with analog sound IF
signal-in, down to processed analog AF-out, is performed on a single chip.
These TV sound processing ICs include versions for processing the multichannel
television sound (MTS) signal conforming to the standard recommended by the
Broadcast Television Systems Committee (BTSC). The DBX noise reduction, or
alternatively, Micronas Noise Reduction (MNR) is performed alignment free.
Other processed standards are the Japanese FM-FM multiplex standard (EIA-J) and
the FM Stereo Radio standard.
Current ICs have to perform adjustment procedures in order to achieve good
stereo separation for BTSC and EIA-J. The MSP34x1G has optimum stereo
performance without any adjustments.
In
case of three or more external sources are used, the video switch IC TEA6415 is
used. The main function of this device is to switch 8 video-input sources on
the 6 outputs.
Each output can be switched on only one of each input. On each input an
alignment of the lowest level of the signal is made (bottom of sync. top for
CVBS or black level for RGB signals).
Each nominal gain between any input and output is 6.5dB.For D2MAC or Chroma
signal the alignment is switched off by forcing, with an external resistor
bridge, 5VDC on the input. Each input can be used as a normal input or as a MAC
or Chroma input (with external Resistor Bridge). All the switching possibilities
are changed through the BUS. Driving 75ohm load needs an external resistor. It
is possible to have the same input connected to several outputs.
The TPA3002D2
is a 9-W (per channel) efficient, Class-D audio amplifier for driving
bridged-tied stereo speakers. The TPA3002D2 can drive stereo speakersas low as
8 &. The high efficiency of the TPA3002D2 eliminates the need for external
heatsinks when playing music.
The
DC voltages required at various parts of the chassis and inverters are provided
by an main power supply unit and power interface board. The main power supply
unit is designed for 24V and 12V DC supply. Power interface board generates
+12V for audio amplifier, 5V and 3.3V stand by voltage and 8V, 12V, 5V and 3V3
supplies for other different parts of the chassis.
An optocoupler is used to control the regulation of line voltage and stand-by
power consumption. There is a regulation circuit in secondary side. During the
switch on period of the transistor, energy is stored in the transformer. During
the switch off period energy is fed to the load via secondary winding. By
varying switch-on time of the power transistor, it controls each portion of
energy transferred to the second side such that the output voltage remains
nearly independent of load variations.
The
microprocessor is embedded inside PW181 chip which also handles scaling, frame
rate conversion and OSD generation. The on-chip 16-bit microprocessor is a
Turbo x86-compatible processor core with on-chip peripherals (timers, interrupt
controller, 2-wire serial master/slave interface, UART, I/O ports, and more).
Special peripherals such as Infrared (IR) pulse decoders and a digital pulse
width modulator (PWM) are also included. There are two independent 2-wire
serial master/slave interface modules that can be multiplexed to control up to
five 2-wire serial ports. The slave 2-wire interface is designed for HDCP use
only (and requires the use of HDCP Image Processors). On-chip RAM of up to 64
Kbytes is available. A complete microprocessor system can be implemented simply
by adding external ROM. The on-chip processor can be disabled to allow external
processor control of all internal functions.

clocked out from the rising edge of the signal applied on VCLK. The device will
switch to the I2C bidirectional mode upon the falling edge of the signal applied

TLC7733
The
TLC77xx family of micropower supply voltage supervisors are designed for reset
control, primarily in microcomputer and microprocessor systems.
During power-on, RESET is asserted when VDD reaches 1 V. After minimum VDD (. 2
V) is established, the circuit monitors SENSE voltage and keeps the reset
outputs active as long as SENSE voltage (VI(SENSE) remains below the threshold
voltage. An internal timer delays return of the output to the inactive state to
ensure proper system reset. The delay time, td, is determined by an external
capacitor:
td = 2.1 x 10 4 x CT
where
CT is in farads
td is in seconds
The TLC77xx has a fixed SENSE threshold voltage set by an internal voltage
divider. When SENSE voltage drops below the threshold voltage, the outputs
become active and stay in that state until SENSE voltage returns above
threshold voltage and the delay time, td, has expired.
In addition to the power-on-reset and undervoltage-supervisor function, the
TLC77xx adds power-down control support for static RAM. When CONTROL is tied to
GND, RESET will act as active high. The voltage monitor contains additional
logic intended for control of static memories with battery backup during power
failure. By driving the chip select (CS) of the memory circuit with the RESET
output of the TLC77xx and with the CONTROL driven by the memory bank select
signal (CSH1) of the microprocessor the memory circuit is automatically
disabled during a power loss. (In this application the TLC77xx power has to be
supplied by the battery.)
The TLC77xxQ is characterized for operation over a temperature range of –40°C
to 125°C, and the TLC77xxI is characterized for operation over a temperature
range of –40°C to 85°C.

is a high-performance, low-power, low-voltage, Si-gate CMOS device and superior
to most advanced CMOS compatible TTL families.
Inputs can be driven from either 3.3V or 5.0V devices. In 3-State operation,
outputs can handle 5V. This feature allows the use of these devices as
translators in a mixed 3.3V/5V environment.
The 74LVC257A is a quad 2-input multiplexer with 3-state outputs, which select
4 bits of data from two sources and are controlled by a common data select
input (S). The data inputs from source 0 (1l 0 to 4l 0 ) are selected when
input S is LOW and the data inputs from source 1 (1l 1 to 4l 1 ) are selected when
S in HIGH. Data appears at the outputs (1Y to 4Y) in true (non-inverting) form
from the selected inputs. The 74LVC257A is the logic implementation of a
4-pole, 2-position switch, where the position of the switch is determined by
the logic levels applied to S. The outputs are forced to a high impedance OFF-state
when OE is HIGH.
The 74LVC14A is a high-performance, low power,
low-voltage Si-gate CMOS device and superior to most advanced CMOS compatible

AD9883A is a complete 8-bit, 140 MSPS, monolithic analog interface optimized
for capturing RGB graphics signals from personal computers and workstations.
Its 140 MSPS encode rate capability and full power analog bandwidth of 300 MHz
supports resolutions up to SXGA (1280 × 1024 at 75 Hz).
The AD9883A includes a 140 MHz triple ADC with internal 1.25 V reference, a
PLL, and programmable gain, offset, and clamp control. The user provides only a
3.3 V power supply, analog input, and Hsync and COAST signals. Three-state CMOS
outputs may be powered from 2.5 V to 3.3 V.
The AD9883A’s on-chip PLL generates a pixel clock from the Hsync input. Pixel
clock output frequencies range from 12 MHz to140 MHz. PLL clock jitter is 500
ps p-p typical at 140 MSPS. When the COAST signal is presented, the PLL
maintains its output frequency in the absence of Hsync. A sampling phase
adjustment is provided. Data, Hsync, and clock output phase relationships are maintained.
The AD9883A also offers full sync processing for composite sync and
sync-on-green applications. A clamp signal is generated internally or may be
provided by the user through the CLAMP input pin. This interface is fully
programmable via a 2-wire serial interface.
Fabricated in an advanced CMOS process, the AD9883A is provided in a
space-saving 80-lead LQFP surface-mount plastic package and is specified over
the –40.˚C to +85. ˚C temperature range.

SAA7118E
The
SAA7118E is a video capture device for applications at the image port of VGA
controllers. Philips X-VIP is a new multistandard comb filter video decoder
chip with additional component processing, providing high quality, optionally
scaled, video.
The SAA7118E is a combination of a four-channel analog preprocessing circuit
including source selection, anti-aliasing filter and ADC, an automatic clamp
and gain control, a Clock Generation Circuit (CGC), a digital multistandard
decoder containing two-dimensional chrominance/luminance separation by an
adaptive comb filter and a high performance scaler, including variable
horizontal and vertical up and downscaling and a brightness, contrast and
saturation control circuit.
It is a highly integrated circuit for desktop video and similar applications.
The decoder is based on the principle of line-locked clock decoding and is able
to decode the colour of PAL, SECAM and NTSC signals into ITU 601 compatible
colour component values. The SAA7118E accepts CVBS or S-video (Y/C) as analog
inputs from TV or VCR sources, including weak and distorted signals as well as baseband
component signals Y-PB -PR or RGB. An expansion port (X-port) for digital video
(bidirectional half duplex, D1 compatible) is also supported to connect to MPEG
or video phone codec.
At the so called image port (I-port) the SAA7118E supports 8 or 16-bit wide
output data with auxiliary reference data for interfacing to VGA controllers.
The target application for the SAA7118E is to capture and scale video images,
to be provided as digital video stream through the image port of a VGA
controller, for capture to system memory, or just to provide digital baseband
video to any picture improvement processing.

The TPS725xx
family of 1-A low-dropout (LDO) linear regulators has fixed voltage options
available that are commonly used to power the latest DSPs, FPGAs, and
microcontrollers. An adjustable option ranging from 1.22 V to 5.5 V is also
available. The integrated supervisory circuitry provides an active low RESET
signal when the output falls out of regulation. The no capacitor/any capacitor
feature allows the customer to tailor output transient performance as needed.
Therefore, compared to other regulators capable of providing the same output
current, this family of regulators can provide a stand alone power supply
solution or a post regulator for a switch mode power supply.
These regulators are ideal for higher current applications. The family operates
over a wide range of input voltages (1.8 V to 6 V) and has very low dropout
(170 mV at 1-A).
Ground current is typically 210 µA at full load and drops to less than 80 µA at
no load. Standby current is less than 1 µA.
Each regulator option is available in either a SOT223–5, D (TPS72501 only), or
DDPAK package. With a low input voltage and properly heatsinked package, the
regulator dissipates more power and achieves higher efficiencies than similar
regulators requiring 2.5 V or more minimum input voltage and higher quiescent
currents. These features make it a viable power supply solution for portable,
battery powered equipment.
Although an output capacitor is not required for stability, transient response
and output noise are improved with a 10-µF output capacitor.
Unlike
some regulators that have a minimum current requirement, the TPS725 family is
stable with no output load current. The low noise capability of this family,
coupled with its high current operation and ease of power dissipation, make it
ideal for telecom boards, modem banks, and other noise sensitive applications.
Features
• 1-A Output Current
• Available in 1.5-V, 1.6-V, 1.8-V, 2.5-V Fixed-Output and Adjustable Versions

flat panel display.
Computer and video images from NTSC/PAL to WUXGA at virtually any refresh rate
can be resized to fit on a fixed-frequency target display device with any
resolution up to WUXGA. Video data from 4:3 aspect ratio NTSC or PAL and 16:9
aspect ratio HDTV or SDTV is supported. Multi-region, nonlinear scaling allows
these inputs to be resized optimally for the native resolution of the display.
Advanced scaling techniques are supported, such as format conversion using
multiple programmable regions. Three independent image scalers coupled with
frame locking circuitry and dual programmable color lookup tables create sharp
images in multiple windows, without user intervention.
Embedded SDRAM frame buffers and memory controllers perform frame rate
conversion and enhanced video processing completely on-chip. A separate memory
is dedicated to storage of onscreen display images and CPU general purpose use. Advanced video processing techniques are
supported using the internal frame buffer, including motion adaptive, temporal
deinterlacing with film mode detection. When used in combination with the new third-generation
scaler, this advanced video processing technology delivers the highest quality
video for advanced displays.
Both input ports support integrated DVI 1.0 content protection using standard
DVI receivers.
A new advanced OSD Generator with more colors and larger sizes supports more
demanding OSD applications, such as on-screen programming guides. When coupled
with the new, faster, integrated microprocessor, this OSD Generator supports
advanced OSD animation techniques.
Programmable features include the user interface, custom start-up screen, all
automatic imaging features, and special screen effects.

SDRAM 4M x 16 (MT48LC4M16A2TG-75)
The
Micron ® 64Mb SDRAM is a high-speed CMOS, dynamic random-access memory
containing 67,108,864 bits. It is internally configured as a quad-bank DRAM
with a synchronous interface (all signals are registered on the positive edge
of the clock signal, CLK). Each of the x4’s 16,777,216-bit banks is orga-nized
as 4,096 rows by 1,024 columns by 4 bits. Each of the x8’s 16,777,216-bit banks
is organized as 4,096 rows by 512 columns by 8 bits. Each of the x16’s
16,777,216- bit banks is organized as 4,096 rows by 256 columns by 16 bits.
Accesses begin with the registration of an ACTIVE command, which is then
followed by a READ or WRITE command. The address bits registered coincident
with the ACTIVE command are used to select the bank and row to be
accessed (BA0, BA1 select the bank; A0-A11 select the row). The address bits
registered coincident with the READ or WRITE command are used to select the
starting column location for the burst access.
The SDRAM provides for programmable READ or WRITE burst lengths of 1, 2, 4, or
8 locations, or the full page, with a burst terminate option. An auto precharge
function may be enabled to provide a selftimed row precharge that is initiated
at the end of the burst sequence.
The 64Mb SDRAM uses an internal pipelined architecture to achieve high-speed
operation. This architecture is compatible with the 2n rule of prefetch
architectures, but it also allows the column address to be changed on every
clock cycle to achieve a high-speed, fully random access. Precharging one bank
while accessing one of the other three banks will hide the precharge cycles and
provide seamless, high-speed, random-access operation.
The 64Mb SDRAM is designed to operate in 3.3V memory systems. An auto refresh
mode is provided, along with a power-saving, power-down mode. All inputs and
outputs are LVTTL-compatible.
SDRAMs offer substantial advances in DRAM operating performance, including the
ability to synchronously burst data at a high data rate with automatic
column-address generation, the ability to interleave between internal banks in
order to hide precharge time and the capability to randomly change column
addresses on each clock cycle during a burst access.
Features
• PC66-, PC100-, and PC133-compliant
• Fully synchronous; all signals registered on positive edge of system clock
• Internal pipelined operation; column address can be changed every clock cycle

FLASH 16Mbit
The
M29W160E is a 16 Mbit (2Mb x8 or 1Mb x16) non-volatile memory that can be read,
erased and reprogrammed. These operations can be performed using a single low
voltage (2.7 to 3.6V) supply. On power-up the memory defaults to its Read mode
where it can be read in the same way as a ROM or EPROM. The memory is divided
into blocks that can be erased independently so it is possible to preserve
valid data while old data is erased. Each block can be protected independently
to prevent accidental Program or Erase commands from modifying the memory.
Program and Erase commands are written to the Command Interface of the memory.
An on-chip Program/Erase Controller
simplifies the process of programming or erasing the memory by taking care of
all of the special operations that are required to update the memory contents.
The end of a program or erase operation can be detected and any error
conditions identified. The command set required to control the memory is consistent
with JEDEC standards. The blocks in the memory are asymmetrically arranged, The
16 KByte Boot Block can be used for small initialization code to start the
microprocessor, the two 8 Kbyte Parameter Blocks can be used for parameter
storage and the remaining 32K is a small Main Block where the application may
be stored. Chip Enable, Output Enable and Write Enable signals
control the bus operation of the memory. They allow simple connection to most
microprocessors, often without additional logic. The memory is offered TSOP48
(12 x 20mm) and TFBGA48 (0.8mm pitch) packages. The memory is supplied with all
the bits erased (set to ’1’).
