MIPI-CSI2 compatible four-channel video decoder targets car surround view

The ISL79985 replaces up to nine discrete components with a single chip to preserve critical board space. It delivers four-channel analog decoding for generating 360-degree around view video to detect objects around the vehicle and assist drivers with backup and parking.
The ISL7998x family also includes the new ISL79986 with a line-interleaved BT.656 interface. The new video decoders provide motorists with detailed, high-quality video, enhancing their ability to see objects around the entire vehicle.
Both chips integrate four analog video decoders with 10-bit ADCs to support four analog camera CVBS inputs simultaneously. The ISL79985’s MIPI-CSI2 interface lowers system EMI, reduces the number of pins compared to a traditional parallel interface, and makes it easy to interface with the newest SOCs and ADAS processors. Both decoders include Intersil’s proprietary automatic contrast adjustment (ACA) image enhancement feature that adapts to rapidly changing lighting conditions. AEC-Q100 Grade-2 qualified for operation from -40°C to +105°C, the chips come in a 7x7mm, 48-lead QFN package.
