To help designers of rearview camera systems which have become mainstream in all new car models worldwide, Intersil has unveiled a full high definition (HD) LCD video processor which instantly displays rearview camera live video. The TW8844 is ideal for center stack/head units, full display rearview mirrors, instrument cluster displays, and dual headrest rear-seat entertainment systems.
The TW8844 video processor with MIPI-CSI2 output and TW8845 video processor with BT.656 output exceed the requirements of the FMVSS-111 law, displaying live video with graphics overlay in less than 0.5 seconds after vehicle ignition.
The new LCD video processor can interface with the latest generation of automotive SoCs. It integrates an analog video decoder, two scalers and MIPI-CSI2 SoC interface.
“The FMVSS-111 law requires that all new vehicles sold in the U.S., beginning in May 2018, have rearview backup cameras and the rear camera video must display in less than two seconds after the driver places the vehicle into reverse gear”, noted the firm. The TW8844 offers the reliability automakers require to ensure their rearview camera systems are compliant with the U.S. Federal Motor Vehicle Safety Standard (FMVSS-111) for preventing injury or death caused by backover accidents.
The TW884x also offers a frozen detection feature which is hardwired to trigger an interrupt signal if thresholds are violated, ensuring the vehicle’s rearview camera is FMVSS-111 compliant and live video is instantly displayed.
The TW884x’s rearview camera bypass architecture decouples the camera-to-display signal path from the rest of the infotainment system, which makes attaining an ISO 26262 functional safety rating on the camera system easier for automakers, stated the firm.
The TW8844 and TW8845 can be used alongside the Renesas’ R-Car SoC family, as well as the ISL78302 dual LDO, ISL78322 dual 2A/1.7A synchronous buck regulator, and ISL78228 dual 800mA synchronous buck regulator to provide power rails for the TW884x, SoC and other key components on the automotive infotainment system board.
The TW8844 video processor with MIPI-CSI2 output is available now in a 14mm x 20mm, 156-lead LQFP package, and is priced at $10.00 USD in 1k quantities.
The processors are AEC-Q100 Grade-2 qualified for operation from -40°C to +105°C.
The TW8845 video processor with BT.656 output is available now in a 14mm x 20mm, 156-lead LQFP package, and is priced at $9.50 USD in 1k quantities.
