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.
