2. General Description

2.1. Introduction

This chapter describes system building blocks in detail.

2.2. System Building Blocks

17MB21 chassis main blocks are as follows:

 Analog Front End : VCTI (Microcontroller + Video Proccessor + Sound Proccessor + IF+

Keyboard/IR Interface+OSD), Audio Amp.

 Back End : TSU33AWL or TSU36AWL (Scaler, Deinterlacer, OSD generator, LVDS

transmitter)

 Side Board(s) : Keyboards, IR/LED Boards, FAV Boards, Headphone Boards.

2.2.1. Analog Front End

17MB21 Main Board consists of two major blocks. The first block is analog front-end and this block is
handled by VCTI chip that is highly multifunctional. This IC does demodulation of Video & Audio
from Tuner IF, CVBS, Audio, RGB, SVHS input selection and processing. It has an audio processor
that supports equalizer or tone control, volume control, AVL, surround effect etc and supplies
amplifier, headphone and CVBS & audio line outputs. It handles video processing such as colour
standard detection and demodulation, picture alignment (brightness, contrast, colour etc.). The IC
also does teletext decoding with fastext memory. After video processing, the processed video is
applied to TSU3XAWL chip in RGB format.

The TV Tuner is an asymmetrical or a symmetrical IF output type and is PLL controlled. The IF
signal is applied single saw filter. After the SAW filter block, IF signal is applied to VCTI IF inputs
(Pin 16 and 17).

As VCTI can handle all the audio processing, there is no need for additional audio processor solution
on the board. VCTI supports three Audio outputs. These outputs are assigned to Line-out,Speaker
and SC1 audio out. The board employs TDA2822M to drive speakers and headphone.

2.2.2. Back End

The Back End section is handled by TSU chip. The RGB input can handle standard interlaced RGB
output from VCTI, PC VGA RGB input and YPbPr. There are two set of ADC is present in TSU which
are assigned to YPbPr/VGA and VCTI RGB output sources.

TSU33AL chip have an integrated 6/8-bit LVDS transmitter.
Backlight dimming and Panel power supply On/Off control is achieved via TSU chip. There are two

pins to control inverter one of them is used for adjusting backlight the other one is used for
backlight on/off control. Backlight on/off control is performed by VCTI.

Each multiplexer has four independent inputs/outputs (pins nY0 to nY3) and a common input output
(pin nZ). The common channel select logics include two digital select inputs (pins So and S1) and an
active LOW enable input (pin
impedance ON-state) with pins S0 and S1. When pin Ē=HIGH, all switches are in the high-
