TW2965 Features
Video Decoder
WD1 (960H) and D1 compatible video decoding operation and each channel is programmable
NTSC (M, 4.43) and PAL (B, D, G, H, I, M, N, N combination), PAL (60) support with automatic format detection
Software selectable analog inputs allows any of 2 CVBS per one video ADC
Built-in analog anti-alias filter
Four 10-bit ADCs and analog clamping circuit for
CVBS input
Fully programmable static gain or automatic gain
control for the Y channel
Programmable white peak control for CVBS channel
4-H adaptive comb filter Y/C separation
PAL delay line for color phase error correction
Image enhancement with peaking and CTI
Digital sub-carrier PLL for accurate color decoding
Digital Horizontal PLL for synchronization processing and pixel sampling
Advanced synchronization processing and sync detection for handling non-standard and weak signal
Programmable hue, brightness, saturation, contrast, sharpness
