PI7VD9008ABH (Obsolete)

Product Description

The PI7VD9008ABH is an AEQ 8-Channel Video Decoder and Audio Codec. A built-in Adaptive equalizer (AEQ) recovers the noisy signals caused by long or small wire gauge Coax cables and displays 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 preview, 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.
