特性 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

 Automatic color control and color killer

 ITU-R 656 like YCbCr(4:2:2) output or time multiplexed output with 36/72/144MHz for WD1 or 27/54/108MHz for D1 format
