Hi,

I am making a VGA based project with Xilinx FPGAs for 640X480 pixel resolution. Can anyone suggest any crystal oscillator value which I can divide to get exactly the pixel rate of 25.175 MHz (or as nearby as possible).

Thanks,
Arvind Gupta.

A simple digikey search reveals it's a standard value https://www.digikey.com/products/en/crystals-oscillators-resonators/oscillators/172?k=&pkeyword=&sv=0&pv2150=u25.175MHz&sf=0&FV=ffe000ac&quantity=&ColumnSort=0&page=1&pageSize=25.
I'm sure other distributors have them is stock too.
