4-Channel 960H Video Decoders and Mixer and Audio Codecs
1. Features
z Video Decoder
ƒ Accepts NTSC (M), PAL (B, D, G, H, I,
M, Nc) and SONY 960H CCD
Camera
ƒ Each 2 of the 4 video decoders
could be programmed to operate at
27 or 36MHz.
ƒ Hardware Fast Switch function
ƒ Fast Switch also controllable by
software or external pin
ƒ Software channel ID in active region
ƒ Four 10-bits video ADCs with built in
9/6.5 MHz analog low pass filter
ƒ Automatic gain control for Luminance
and Chrominance
ƒ Programmable brightness, contrast,
saturation, hue, and sharpness
ƒ 5-H comb filter for YC separation
ƒ Chrominance line filter for PAL phase
error
ƒ DLL for video synchronization,
supports 27MHz crystal within
+/-1000 ppm variance
ƒ Advanced video synchronization for
weak and noisy CVBS. Supports
video signal transmitted by
500-meter long cable
ƒ Up to 3 CCIR656 output interfaces
which could be configured as 3 sets
of CCIR656 (36/27MHz) or 3 sets of
TDM2 (72/54MHz) or 3 set of TDM4
(144/108MHz)
ƒ Support line lock camera
z Audio Codecs
ƒ Five audio ADCs and one audio
DAC are integrated
ƒ Master I2S/DSP playback, record
and audio-mixing
ƒ Supports extended I2S/DSP format
transmitting up to 16 audio channels
using one data pin
ƒ Audio cascade up to 16 channels

format
z Video Mixer
ƒ Two SD mixers and one HD mixer.
Each mixer supports up to 4
channels
ƒ Two SD CCIR656 outputs
(36/27MHz) or one HD SMPTE
274M output (74.25MHz)
ƒ One TDM4 (144/108MHz) output
ƒ One optional TDM4 input as mixer
video sources.
ƒ Various mixing combinations.
Special H partition supported
