No, the PCB is not already build.
I understand that the ADV7343 does not support the timing that is required for VGA/XGA.
The plan was to use the ADV7343 for this case only as DAC to output the RGB 4:4:4 data ( 24-bit pixel input)
from the Video-Source FPGA . HSYNC and VSYNC will not be routed to the ADV7343 but directly from the Video Source FPGA to TTL Buffers. A pipeline delay within the ADV7343 could be managed by the FPGA to align HSYNC/VSYNC with the analogue Signal from ADV7343.
