TUNER(MXL601)
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.

AUDIO AMPLIFIER
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. Awfully 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.

Cable : PW25, PW26, PW82-3, PW03, PW04, PW06, PW07
The power supplies generate 24V, 12V, 5V, 3,3V and 12V, 5V, 3.3V stand b y 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 f or protecting chassis and main IC against dam ages 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.
