Intersil – ISL79985: Industry’s First Four-Channel Video Decoder with MIPI-CSI2


The ISL79985 integrates four high quality NTSC/PAL/SECAM video decoders that convert the analog composite video signal to digital component YCbCr data for automotive applications. Each channel contains a 10-bit ADC that supports single-ended, differential, and pseudo differential composite video inputs, proprietary clamp and gain controllers, thus, utilizes a 4H-comb filter for separating luminance and chrominance to reduce cross noise artifacts. ISL79985 also features integrated short-to-battery and short-to-ground detection, advanced image enhancement capabilities such as the programmable Automatic Contrast Adjustment (ACA), and the MIPI-CSI2/ITU-R BT.656 output interface.
