CrossLink from Lattice Semiconductor is a programmable video bridging device that supports a variety of protocols and interfaces for mobile image sensors and displays. The device is based on Lattice mobile FPGA 40-nm technology. It combines the extreme flexibility of an FPGA with the low power, low cost and small footprint of an ASIC. CrossLink supports video interfaces including MIPI DPI, MIPI DBI, CMOS camera and display interfaces, OpenLDI, FPD-Link, FLATLINK, MIPI D-PHY, MIPI CSI-2, MIPI DSI, SLVS200, subLVDS, HiSPi and more. Lattice Semiconductor provides many pre-engineered IP (Intellectual Property) modules for CrossLink. 

By using these configurable soft core IPs as standardized blocks, designers are free to concentrate on the unique aspects of their design, increasing their productivity. The Lattice Diamond design software allows large complex designs to be efficiently implemented using CrossLink. Synthesis library support for CrossLink devices is available for popular logic synthesis tools. The Diamond tools use the synthesis tool output along with the constraints from its floor planning tools to place and route the design in the CrossLink device. 

The tools extract the timing from the routing and back-annotate it into the design for timing verification. Interfaces on CrossLink provide a variety of bridging solutions for smart phone, tablets, wearables, VR, AR, Drone, Smart Home, HMI as well as adjacent ISM markets. The device is capable of supporting high-resolution, high-bandwidth content for mobile cameras and displays at 4 UHD and beyond.
