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.
