Probably the most popular of the D-PHY specifications is CSI, or camera serial interface. This is the common I/O standard interface for the camera sensor devices which are driving much of the interest. Efinix finds that engineers commonly need to connect multiple cameras together or bridge between MIPI/CSI and another bus interface and additionally will need in-line processing functions. With the hardened block, all the CSI and D-PHY functions are done for the customer, so they do not need to use any valuable FPGA logic elements. Efinix is compliant with CSI-2 v1.3 and the hardened core supports up to 4 virtual channels.
