OBSOLETE - PART DISCONTINUED New Product Brief Product Databrief PI7VD9004ABH AEQ 4-Channel 960H Video Decoder with 10-bit Audio ADC PI7VD9004ABH is a built-in AEQ (AdaptiveEqualizer) 4-Channel Video Decoder and Audio Codec for video security and surveillance applications. Video Decoder converts analog video composite signals (CBVS) to digital video formats (ITU-R BT.656). Pericom AEQ technology recovers degraded signals and delivers highly improved picture images to Video Processor, damaged by long distance cables, small wire gauge cables or low-end poor quality cables. In addition of Adaptive Comb Filter Y/C separation and Resilient sync-tip algorithm, AEQ video decoder products will delivers 2x picture image clarity with artificial noise reduction comparing to other conventional products The video resolutions of NTSC/PAL and WD1(960H) are both supported with single 27MHz reference crystal clock frequency. The converted video streams are transported as the time multiplexed format to dual or quad-channel outputs. Each of audio channels contains 10-bit ADC. A built-in audio digital controller can generate I2S outputs for recording/mixing and accepts as the inputs for playback as well.
