Combine2 (IC6005) is an FPGA. It functions by reading data stored in the SPI
Flash ROM (IC6004) and performs configuration.

The 10-bit 3ch video signal and sync signal output from REON (IC3001) are re-
synchronized with SSCLK (XGA: 65MHz, WXGA: 85MHz), spread spectrum
signal, output from Clock Generator (IC4702). Then the signal is output as a 10-
bit 3ch video signal.
