説明
The ISL79985, ISL79986 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. 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 make the ISL79985, ISL79986 an ideal solution for demanding automotive around view applications.
