TW8832, TW8832S

TFT Display Controller

Analog RGB Inputs

 Triple high speed 10-bit ADCs with clamping and

programmable gain amplifier

Description

The TW8832 incorporates many of the features

required to create multi-purpose in-car LCD display

system in a single package. It integrates a high

quality 2D comb NTSC/PAL/SECAM video decoder,

triple high speed RGB ADCs, high quality scaler, and

images enhancement functions, which include Black

and White Stretch, etc. It also supports panoramic

scaling for conversion to wide screen display. On the

input side, it supports a rich combination of CVBS, S-

video, analog RGB as well as digital inputs. On the

output side, it supports a variety of digital panel types

with its built-in timing controller.

 SOG and H/V sync support for YPbPr or RGB input

 Built-in line locked PLL with sync separator

 Support analog input resolution up to 1080i or

WXGA

Digital Inputs Support

 Support 656 video formats

TFT Panel Support

 Built-in programmable timing controller

 Supports 3, 4, 6 or 8 bits per pixel up to 16.8

million colors with built-in dithering engine

Applications

 In-car display controller

 Portable DVD and DVRs players

 Portable media player

 Support digital panel up to WVGA/SVGA resolution

 Support Serial (8-bit) RGB panel

On Screen Display

Features

 Four windows font OSD with bordering / shadow

Analog Video Decoder

 Supports bit-mapped based OSD through SPI

(TW8832S only)

 NTSC (M, 4.34) and PAL (B, D, G, H, I, M, N, N

combination), PAL (60), SECAM with automatic

format detection

Image Processing

 High quality scaler with both up/down and

nonlinear scaling support

 Three 10-bit ADCs and analog clamping circuit

 Fully programmable static gain or automatic gain

 Built-in 2D de-interlacing function

control for the Y or CVBS channel

and sharpness

 Programmable white peak control for the Y or CVBS

channel

 Supports programmable cropping of input video

and graphics

 Software selectable analog inputs

 High quality adaptive 2D comb filter for both NTSC

 Independent RGB gain and offset controls

 Panorama/Water-glass scaling

and PAL inputs

 PAL delay line for color phase error correction

 Programmable 10-bit Gamma correction for each

color

 Image enhancement with 2D dynamic peaking and

CTI

 Operated in Frame Sync mode

 Black/White Stretch

 Digital sub-carrier PLL for accurate color decoding

 Digital horizontal PLL and Advanced

synchronization processing for VCR playback and

weak signal performance

 Programmable hue, brightness, saturation, contrast

and sharpness

 High quality horizontal and vertical filtered down

scaling with arbitrary scale down ratio
