MxL601
is a highly integrated low-power silicon tuner IC targeting all global analog
and digital cable standards as well as digital terrestrial reception standards.
Broadband input filtering and channel filtering have been completely integrated
on-chip. This integration enables a very compact design requiring a small
footprint, low bill-of-materials cost, and low power consumption. A signal at
the 753 RF input is filtered and converted to a programmable IF output up to
44MHz. Automatic gain control, LO generation, and channel selectivity functions
are completely integrated on the chip, which simplifies board level design. All
functions of the IC can be controlled via I2C interface. MxL601 is available in
a 4 x 4 mm2 24-pin QFN package.
Features :
* Tuning range from 44MHz to 1002MHz
* Programmable channel bandwidths of 6, 7,and 8MHz
* Integrated channel filtering requiring no external SAW filter for digital applications

The TAS5721 is a 15-W stereo or 2x10 W + 1x15 W2.1 device,
efficient, digital audio-power amplifier for driving stereo bridge-tied
speakers. One serial data input allows processing of up to two discrete audio
channels and seamless integration to most digital audio processors and MPEG
decoders. The device accepts a wide range of input data and data rates. A fully
programmable data path routes these channels to the internal speaker drivers.
The TAS5721 is a slave-only device receiving all clocks from external sources.
The TAS5721 operates with a PWM carrier between a 384-kHz switching rate and a
352-KHz switching rate, depending on the input sample rate. Oversampling
combined with a fourth- order noise shaper provides a flat noise floor and
excellent dynamic range from 20 Hz to 20 kHz.

POWER STAGE
The DC voltages required at various parts of the chassis and panel are provided by a main power supply unit. MB82S chassis can operate with PW05, IPS60, IPS70, IPS16, IPS17, IPS19, PW25, PW26, PW82-3, PW03, PW04, PW06, PW07 as main power supply and also with 12V adaptor.
Which power board can be used for board to board or cable connection?
Board to board (BTB) : PW05, IPS60, IPS70, IPS16, IPS17, IPS19
Power Cable : PW25, PW26, PW82-3, PW03, PW04, PW06, PW07
The power supplies generate 24V, 12V, 5V, 3,3V and 12V, 5V, 3.3V stand by mode DC voltages. Power stage which is on-chassis generates 5V, 3V3 stand by voltage and 12V, 8V, 5V, 3V3, 2.5V, 1,8V and 1,2V supplies for other different parts of the chassis. Chassis block diagram is indicated below.
The blocks on power block diagram is using dependent to main supply. For PW26 and PW27 just common blocks are enough for proper operation.
Short CCT Protection Circuit
Short circuit protection is necessary for protecting chassis and main IC against damages when any Vcc supply shorts to ground. Protect pin should be logic high while normal operation. When there is a short circuit protect pin should be logic low. After any short detection, SW forces LEDs on LED card to blink.

DDR3 SDRAM 1Gb G-die
Description:
The 1Gb DDR3 SDRAM G-die is organized as a 8Mbit x 16 I/Os x 8banks device. This synchronous device achieves high speed double-data-rate transfer rates of up to 2133Mb/sec/pin(DDR3-2133)for general applications. The chip is designed to comply with the following key DDR3 SDRAM features such as posted CAS, Programmable CWL, Internal (Self) Calibration, On Die Termination using ODT pin and Asynchronous Reset . All of the control and address inputs are synchronized with a pair of externally supplied differential clocks. Inputs are latched at the cross point of differential clocks (CK rising and CK falling). All I/Os are synchronized with a pair of bidirectional strobes (DQS and DQS) in a source synchronous fashion. The address bus is used to convey row, column, and bank address information in a RAS/CAS multiplexing style. The DDR3 device operates with a single 1.5V ± 0.075V power supply and 1.5V ± 0.075V VDDQ. The 1Gb DDR3 G-die device is available in 96ball FBGA(x16).
