TW8823C

TFT Flat Panel Controller with Built-In 3D Video

Decoder, Triple ADCs, Dual PIP, and 16-Bit OSD Support

The TW8823C incorporates many of the features

 Digital sub-carrier PLL for accurate color decoding

required to create a multi-purpose in-car LCD display

system into a single package. It integrates a high-quality

3D comb NTSC/PAL/SECAM video decoder, triple high

speed RGB ADCs, high-quality scaler, bit-mapped OSD,

triple DACs and image enhancement functions that

include features such as Black and White Stretch and

favorite color enhancement. It also supports panoramic

scaling for conversion to wide screen display format. On

the input side, it supports a rich combination of CVBS,

S-video, analog RGB, and digital YCbCr/RGB. On the

output side, it supports both digital and analog panel

types with its built-in timing controller and analog RGB

output. In addition, the TW8823C supports LVDS type

panels.
