hello, all friends:
We want to design a chip to encode VGA signal(vsync rate
is 50hz or 60hz) to TV signal. we can only use line buffer,
any one can tell me how to design such a chip, we
now have datasheet of CH7013A and VIA1622,
but from datasheet, I don't understand how their chip
works.
I want a detailded architecture for such a chip?
The biggest problem that we encountered is
how to synchronous input vsync and output
vsync.
any comments are welcomed.
help me !!!
best regards
