IC converts cockpit, infotainment video signals
Seiko Epson has developed a new interface conversion IC for in-vehicle systems that converts eDP (Embedded DisplayPort) video signals to OpenLDI (open LVDS display interface).

Both eDP and OpenLDI are interface standards for transmitting video signals to displays, but eDP supports higher resolution video and faster speeds than the more widely used OpenLDI. The new product is compliant with AEC-Q100 and operates at temperatures up to 105℃.

The conversion IC is also equipped with safety functions required for automotive systems. For example, a CRC function monitors whether video signals output from an ECU are being properly received, and a blank screen function masks the display with a particular image pattern when a problem is detected in the transmission path between an ECU and the conversion IC. The IC supports the design of dual-display instrument clusters, with a splitter function that splits and outputs video signals on two displays. The chip operates from 3.3V, it has two eDP 1.4a lanes supporting up to 2.7 Gbps for its input and two OpenLDI-Tx channels, supporting up to 154MHz/channel.
