    Crystal oscillator value for FPGA based VGA project

    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/...=1&pageSize=25.
    I'm sure other distributors have them is stock too.
