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.

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.

device that sends data onto the bus is defined as transmitter, and a device
receiving data as receiver. The bus must be controlled by a master device which
generates the Serial Clock (SCL), controls the bus access, and generates the
START and STOP conditions, while the 24C32A works as slave. Both master and
slave can operate as transmitter or receiver but the master device determines
which mode is activated

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.

MSP34X1G-MSP3411G Multistandard Sound Processor Family
The
MSP 34x1G 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.
Figure shows a simplified functional block diagram of the MSP 34x1G.
The MSP 34x1G has all functions of the MSP 34x0G with the addition of a virtual surround sound feature.
Surround sound can be reproduced to a certain extent with two loudspeakers. The MSP 34x1G includes the Micronas virtualizer algorithm “3D-PANORAMA” which has been approved by the Dolby 1) Laboratories for with the "Virtual Dolby Surround" technology. In addition, the MSP 34x1G includes the “PAN-ORAMA” algorithm.
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 MSP 34x1G has optimum stereo performance without any adjustments.
The MSP 34x1G has built-in automatic functions: The IC is able to detect the actual sound standard automat-ically (Automatic Standard Detection). Furthermore, pilot levels and identification signals can be evaluated internally with subsequent switching between mono/stereo/bilingual; no I 2 C interaction is necessary (Automatic Sound Selection).

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.

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.

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’).
