Description
PI7VD9008ABH is AEQ 8-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.
