Each channel contains a 10-bit ADC Software-selectable analog input control allows for that supports single-ended, differential, and pseudo combinations of single-ended CVBS and differential CVBS differential composite video inputs. The ISL79987 and ISL79988 use a 4H-comb filter for separating luminance and Integrated, four-video analog anti-aliasing filters and 10-bit chrominance to reduce cross noise artifacts, and proprietary CMOS ADCs with differential and single-ended inputs clamp and gain controllers. Integrated short-to-battery and Fully programmable static gain or automatic gain control for short-to-ground detection, advanced image enhancement the Y-channel capabilities such as the programmable Automatic Contrast Programmable white peak control for the Y-channel Adjustment (ACA), and the MIPI-CSI2/ITU-R BT.656 output interface make the ISL79987 and ISL79988 an ideal solution 4-H adaptive comb filter Y/C separation for the demands of automotive around view applications.
