4-Channel 960H Video Decoders and Audio Codecs
1. Features
z Video Decoder
 Accepts NTSC (M), PAL (B, D, G, H, I,
M, Nc) and SONY 960H CCD
Camera
 Each 2 of the 4 video decoders
could be programmed to operate at
27 or 36MHz.
 Hardware Fast Switch function
 Fast Switch also controllable by
software or external pin
 Software channel ID in active region
 Four 10-bits video ADCs with built in
9/6.5 MHz analog low pass filter
 Automatic gain control for Luminance
and Chrominance
 Programmable brightness, contrast,
saturation, hue, and sharpness
 5-H comb filter for YC separation
 Chrominance line filter for PAL phase
error
 DLL for video synchronization,
supports 27MHz crystal within
+/-1000 ppm variance
 Advanced video synchronization for
weak and noisy CVBS. Supports
video signal transmitted by
500-meter long cable
 Up to 5 CCIR656 output interfaces
which could be configured as 5 sets
of CCIR656 (36/27MHz) or 3 sets of
TDM2 (72/54MHz) or 3 set of TDM4
