Overview

The ISL79987 and ISL79988 integrate four, high-quality NTSC/PAL/SECAM video decoders that convert analog composite video signals 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. The ISL79987 and ISL79988 use a 4H-comb filter for separating luminance and chrominance to reduce cross noise artifacts, and proprietary clamp and gain controllers. 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 ISL79987 and ISL79988 an ideal solution for the demands of automotive around view applications.
