Programmable devices provide interface bridge for ADAS
Programmable devices from Lattice Semiconductor expand the Lattice Semiconductor automotive product portfolio to include the ECP5 and CrossLink devices tailored for interface bridging applications.
They can be used for connectivity in ADAS (advanced driver assistance systems) and infotainment applications, while also bridging the gap between emerging image sensor and video display interfaces with legacy automotive interfaces, says the company.
Ideally each device in an automotive system would interface directly to the applications processor, but this is not always the case. The increase in mobile platforms in automotive applications compounds the problem, but interface bridging devices can support a range of interfaces and protocols including MIPI D-PHY, MIPI CSI-2, MIPI DSI as well as legacy video interfaces and protocols such as CMOS, RGB, MIPI DPI, MIPI DBI, SubLVDS, SLVS, LVDS and OpenLDI.
A proliferation of cameras and sensors inside vehicles has resulted in interface mismatches between mobile image sensors, application processors, and embedded displays. The ECP5 and CrossLink devices enable developers to adopt cameras and displays with the latest mobile interface technology to reduce overall system cost, power and size, as well as accelerating time-to-market, explains the company.
The CSP5 is cost-optimised architecture with high-speed SerDes channels to provide video interfaces to Open LDI, LVDS FPD-Link, eDP, PCIe and GigE. It is low power consumption and in small packages, with high functional density. In addition to pre/post processing (i.e. image signal processing), there is software support in the form of the Lattice Diamond 3.8.
CrossLink is claimed to be the world’s fastest MIPI D-PHY bridging device that delivers up to 4K UHD resolution at 12Gbit/s bandwidth. It supports popular mobile, camera, display and legacy interfaces such as MIPI D-PHY, MIPI CSI-2, MIPI DSI, MIPI DPI, CMOS, and SubLVDS and LVDS. It is offered in what the company claims is the industry’s smallest package size, with a 6mm2 option.
