LatticeECP3 Video Protocol Board
The LatticeECP3™ FPGA family includes many features for video applications. For example, DisplayPort, SMPTE standards (SD-SDI, HD-SDI and 3G-SDI), DVB-ASI, DVI and HDMI can be implemented with 16 channels of embedded SERDES/PCS. 7:1 LVDS video interfaces like ChannelLink and CameraLink can be supported by the generic DDRX2 mode on the I/O pins. When configuring to TRLVDS mode, the I/O pins on banks 0 and 1 can also be used to receive the TMDS signals of DVI or HDMI video standard.

This user’s guide describes revision C of the LatticeECP3 Video Protocol Board featuring the LatticeECP3 LFE3-95E-7FN1156C FPGA device. The stand-alone evaluation PCB provides a functional platform for development and rapid prototyping of many different video applications.
