1. INTRODUCTION

1.1. Scope

The document covers 20” (17MB18) chassis building blocks, basic features, service menu settings, and the other information needed by service personal.

• Equalizer

• IR Control (RC5)

• OSD;Menu Languages ENG, FRA, GER, ITA, SPA, POR, TUR, SWE, D EN, FIN, NOR, POL, HUN, CZE, BUL,

ARA, PER, RUS (subject to change and be grouped)

• Teletext

• 2H/4H Comb Filter

• White balance settings (warm/normal/cool) for TV&PC

• Full AIR&CABLE band coverage

• Auto Shut down

2. SYSTEM BUILDING BLOCKS

17MB18 chassis main blocks are as follows:

• Analog Front End : UOCIII (Microcontroller + Video Proccessor + Sound Proccessor + IF), CTI, Tuner, SAW

filters, Audio Amp., DAC

• Back End : PW1306(Microcontroller, Scaler, OSD, Keyboard/IR Interface)

• Side Board(s) : Keyboards, IR/LED Boards, TTL Panel Interface Cards, VCbCr Input Board (Optional)

2.1. Analog Front End

17MB18 Main Board consists of two major blocks. The first block is analog front-end and this block is handled by UOCIII 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 10 pages text memory. After video processing, the processed video is applied to PW1306 chip in RGB format.

The TV Tuner is an asymmetrical IF output type and is PLL controlled. For multistandard reception, a switch able SAW filter is used as the sound filter and it is controlled by SAW_SW output from UOC. After the SAW filter block, IF signal is applied to UOC IF inputs (VIFIN[1,2] and SIF[1, 2]).

As UOCIII can handle all the audio processing, there is no need for additional audio processor solution on the board. UOC supports three Audio outputs. These outputs are assigned to Headphone, Speaker and Scart Audio line outputs. The board employs TDA7056A and TDA1308 to drive speaker and headphone outputs respectively. As another dedicated output for Audio Line out from jack is not possible in UOC, this line out signal is obtained by using I2S input DAC CS4335. UOCIII I2S output is converted to anolog signal by DAC CS4335.

2.1.1.

Tuner

As the thickness of the TV set has a limit, a horizontal mounted tuner with longer connector is used in the product. The tuning is available through the digitally controlled I

C bus (PLL). Below you will find info on the

Asymmetrical Tuner in use.

General description:

The tuner meets a wide range of applications. It is a combined VHF, UHF tuner suitable for CCIR systems B/G, H, L, L’, I and I’. The low IF output impedance drives a wide variety of SAW filters with sufficient suppression of triple transient.

Features:

•

Small sized UHF/VHF tuners Systems CCIR: B/G, H, L, L’, I and I’; OIRT: D/K

•

Digitally controlled (PLL) tuning via I

•

Off-air channels, S-cable channels and Hyper band

•

2.1.2.

K3953M is an IF Filter for Video Applications. The package is SIP5K. Supported standards are B/G, D/K, I, L/L’. K9656M is an IF Filter for Audio Applications. The package is SIP5K. Supported standards are B/G, D/K, I, L/L’.

2.2. Back End

The Back End section is handled by PW1306 chip. This IC has built in ADC’s for RGB and SOY support. The RGB input can handle standard interlaced RGB output from UOC, PC VGA RGB input. As only 1 set of ADC is present in PW1306 these sources should be multiplexed. All the multiplexing operations are controlled by PW1306 via YUV_TV_SW (58) and VGA_TV_SW (57) signals.

The video output from PW1306 is a 48-bit digital RGB bus format and made available on two separate connectors with TTL control signals (i.e. HS, VS, CLK, etc.). This digital output is intended to interface to TTL compatible display devices. As PW1306 does not have integrated LVDS transmitter, 24 bit (even part of RGB) video output and TTL control signals from PW1306 are also inputted to DS90C385 LVDS IC to produce single pixel LVDS output for LVDS compatible LCDs.

3.3. PW1306

The PW1306 Video Image Processor is a “system-on-a-chip ” that oversamples and processes RGB or YPbPr video from analog video decoders. The PW1306 integrates video processing, including deinterlacer and video enhancement filters with a triple ADC. Analog RGB or YPbPr in PC graphics, standard, or high-definition video can be disp layed in either 4:3 or 16:9 formats.

• Supports analog video decoders with tri pl e 8-bit Analog-to-Digital Converters (ADCs) up to 140 MSPS conversion rate

• Supports Sync-on-Green (SOG), Sync-on-Luma (SOY),and Composite sync inputs

• 1080i/720p/480p HDTV; 480i and 576i NTSC/PAL SDTV; PC graphics (up to SXGA)

• YPbPr/YCbCr/YUV-to-RGB Color Space Converter with programmable coefficients

• On-chip, bitmap-based, OSD controller with on-chip memory

• 24/30/48-bit RGB output with 135 MPixels/second maximum output rate
