Dear Analog Device Company Support:
We have EVAL-ADV7401/3EBZ to evaluate the conversion of non-standard video to
standard VGA output values.
The source of video to convert is based on the video outputs of the chip
ADV7401KP50E for RS-343/RS-170 RGB sync on all channels, 807 lines 2:1
interlaced, this signal is connected directly to VGA input port (P1) by the
settings specified inthe application note (AN-0978).
Apparently this signal is recognized but I could not make the proper settings
for the desired results, except once for a configuration script to output
resolution 640x480 @ 60 per port P11, but with vertical refresh problems.
The problem that I have always had has been caused by the vertical especially
since this system has a 76-hertz vertical sync and horizontal sync 30,556
If there is any other solution or any sricpt other than those already seen
(Ver.1.2, Ver.1.3) that could guide me to an early solution to this particular
video would appreciate.
Note: There is some compiler C/C++ for this eval-board?.
