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
combination), PAL (60), SECAM with automatic
format detection
Three 10-bit ADCs and analog clamping circuit
Fully programmable static gain or automatic gain
control for the Y or CVBS channel
Programmable white peak control for the Y or CVBS
channel
Software selectable analog inputs
High quality adaptive 2D comb filter for both NTSC
and PAL standards
PAL delay line for color phase error correction
Image enhancement with 2D dynamic peaking and
CTI
Digital sub-carrier PLL for accurate color decoding
Digital horizontal PLL and Advanced synchronization
processing for VCR playback and weak signal
performance
