Video Decoder 1ADC 10-Bit 128-Pin LQFP Tray

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. High quality Live 4-Channel Video/Audio decoder with WD(960H) and NTSC/PAL camera support Built-in Proprietary Adaptive Equalizer (AEQ) delivers 2x Picture Image Clarity or 2x long distance cables with Adaptive Comb Filter design optimized for weak, noisy, or unstable signal recovery Saving installation cost by eliminating signal amplifier around the 500-800 meter Coax cable installation Resilient Sync-tip detection to lock video signal in a noisy environment with programmable luminance peaking to enhance sharpness, hue, saturation, contrast, brightness supports Flexible ITU-R BT.656 time multiplexed video outputs with 27/54/108 MHz or 36/72/144 MHz Accepts NTSC(M), NTSC 4.43, PAL(B, D, G, H, I, M, Nc) and PAL60 with single 27 MHz reference clock 4-Channel Composite Video or 2-channel S-video Inputs Fully differential CMOS analog pre-processing channel with clamping Automatic gain control (AGC) for the best signal tonoise performance. Switch to B/W mode while the input signal is weak. Complementary 5H adaptive comb filters for both cross-luma and cross-chroma noise reduction Built-in 10-bit audio Codec to allow 5 audio inputs, single audio output with Mixed audio analog output for multiple audio channels Two serial audio formats (I2S and DSP) are supported for recording/mixing output and playback input Î Selectable Master and Slave serial audio interface Low power consumption during operation or power-down mode Two-wire serial interface(I2C) for brightness, contrast, saturation, hue, and sharpness control Packages: 128-pin LQFP
