ContributorGTS Transceiver PHY - Reference Clock Network
I am trying to understand the GTS Clocking Network. In the user guide doc here, it is possible to see the following suggested design: However later in the doc, we can see this state...
Hi,
Apologies for the delayed response.
As I understand it, you have some questions regarding the connections for i_rx_cdr and i_tx_pll of the PHY, as well as i_refclk for the system PLL. For your reference, in the example design, all three reference clocks are configured to operate at the same frequency. Therefore, it is recommended to connect them to the same clock source.
Please let me know if you have any concerns or need further clarification. Thank you!
