A customer on our website asked the following question:
Hi,
Could you please clarify what the onboard oscillator of the Cmod A7 is? The schematic shows a 100 MHz MEMS oscillator, but it's tied to the USB-12MHz line and the constraints file lists a period of 83.33 ns. The Artix 7 AC/DC data sheet also lists a minimum PLL input frequency of 19 MHz.
