MHL receiver chips meet automotive specs

December 16, 2014 // By Christoph Hammerschmidt
MHL, the mobile interface de-facto standard that connects smartphones and similar devices to high-definition displays, is gaining popularity. Chipmaker Silicon Image joins the MHL camp by rolling two MHL receiver ICs engineered to meet automotive requirements. In cars, MHL is used to connect smartphones to the vehicle's infotainment system display.

Silicon Image's new MHL receivers qualified for automotive deployment according to AEC Q-100 and designed for operation in a wide temperature range. The chips are available in two versions: The SiL5293 has an RGB output whereas the SiL5620 comes with a CSI-2 output.

MHL supports up to 4K Ultra HD video, with up to eight channels of digital audio, all while charging the mobile device. The high performance and responsiveness of MHL makes it an ideal connectivity technology for the connected car and infotainment units, enabling drivers to navigate GPS and music apps from the phone. MHL also enhances rear-seat entertainment systems by displaying the latest movies and games from a phone to the rear screen of the car. MHL technology addresses the fundamental issue of connecting two ecosystems with such vastly different development lifecycles as the smartphone and the car by keeping all of the video processing and rendering on the phone as uncompressed video over MHL.
