TFT Display Controller

TW8833, TW8833S

Applications

• In-car display controller

• Portable DVD and DVRs players

• Portable media player

Description

The TW8833 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, triple DACs and

images enhancement functions, which include Black

and White Stretch and 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 and analog component inputs. On the output

side, it supports analog panel type with its built-in

timing controller.

Analog Video Decoder

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

• Three 10-bit ADCs and analog clamping circuit

• Fully programmable static gain or automatic gain

• Programmable white peak control for the Y or CVBS

• Software selectable analog inputs

• High quality adaptive 2D comb filter for both NTSC

• PAL delay line for color phase error correction

• Image enhancement with 2D dynamic peaking and

• Digital sub-carrier PLL for accurate color decoding

• Digital horizontal PLL and Advanced synchronization

• Programmable hue, brightness, saturation, contrast

• High quality horizontal and vertical filtered down
