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, and proprietary clamp and
gain controllers. The ISL79987 and ISL79988 utilizes 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.
