PI7VD9004ABH Datasheet, PDF (1/53 Pages) Pericom Semiconductor Corporation – Adaptive EQ 4-channel 960H Video Decoder

Features
 Real time AEQ 4-channel Video/Audio decoder
for WD1(960H) and D1 cameras
 Built-in Adaptive Equalizer(AEQ) for the best
picture image in the several hundred meter coax
cable condition
 Proprietary Pericom AEQ technology recover
weak, noisy, or unstable analog input signals
 Resilient SYNC TIP detection to lock video
signal in a noisy environment

Description
PI7VD9004ABH is AEQ 4-Channel Video Decoders
and Audio Codec. Built-in Adaptive equalizer
(AEQ)recover the noisy signals caused by long or
small wire gauge Coax cables and display the best
picture image view quality. The video decoder
converts NTSC, PAL analog composite video
broadcasting signal (CVBS) into digital components
YCbCr for video controller or processor to perform
pre-view, compression and storage etc. The converted
digital video streams complying with ITU-R BT.656
are transported in time multiplexed format, which
contains one, two or four video channels.
Single 27MHz reference crystal clock support NTSC,
PAL and 960H standard resolution. Each video
channel contains 10-bit ADC, proprietary clamp,
automatic gain controller and 5H comb filter for
separating luminance & chrominance to reduce
artificial noise.
Application
 Video Security DVRs, PC-DVR, Video Capture
cards
 Automotive Camera Driver Assistant Systems
 Video Broadcasting Equipment
