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.
