Quad video decoder targets vehicle safety

The TW9984 four-channel analog video decoder/encoder targets vehicle around-view parking assist applications and advanced driver assistance systems (ADAS). The chip is said to replace up to nine discrete components and accepts all NTSC and PAL standards with auto detection.

The IC processes and combines input from four video cameras into a single top-down view as if a camera was stationed directly above the vehicle. It has four anti-aliasing filters and 10-bit CMOS A/D converters with differential and single-ended inputs. The chip supports 108 MHz time multiplexed ITU-R BT.656 format output for four channels over a single 8-bit data bus. It consumes approximately 100 mW per decoder channel and is AEC-Q100 qualified.
