VGA Port

The five standard VGA signals Red, Green, Blue, Horizontal Sync (HS), and Vertical Sync (VS)

available at the VGA connector arise from the FPGA (sync signals) and an Analog Devices ADV7125

high speed video DAC (color signals). The video DAC presents three parallel 8-bit data ports to the
