Dear all,

 

Issue : CSYNC generation from HSYNC and VSYNC .

 

I am using  http://www.epanorama.net/circuits/vga2rgbs_ttl.gif  mentioned circuit in my designing.and

I am converting CSYNC from HSYNC and VSYNC which  is coming from VGA connector.

 

1.Is generated CSYNC timings are 64 us where 4.7us (active low pulse) and 59.3us (active high pulse) ?

2.or inverted of above(point 1) mentioned pulse ?

 

Note : In simulation I am note able to generate the perfect timings of HSYNC and VSYNC.
