CrossLink™-NX family of low-power FPGAs can be used in a wide range of applications, and are optimized for bridging and processing needs in Embedded Vision applications – supporting a variety of high bandwidth sensor and display interfaces, video processing and machine learning inferencing. It is built on Lattice Nexus FPGA platform, using low-power 28 nm FD-SOI technology. It combines the extreme flexibility of an FPGA with the low power and high reliability (due to extremely low SER) of FD-SOI technology, and offers small footprint package options.

CrossLink-NX supports a variety of interfaces including MIPI D-PHY (CSI-2, DSI), LVDS, SLVS, subLVDS, PCI Express (Gen1, Gen2), SGMII (Gigabit Ethernet), and more.

Processing features of CrossLink-NX include up to 39K Logic Cells, 56 18x18 multipliers, 2.9 Mb of embedded memory (consisting of EBR and LRAM blocks), distributed memory, DRAM interfaces (supporting DDR3, DDR3L, LPDDR2, and LPDDR3 up to 1066 Mbps x 16 data width).
