The following table describes the two clocks that are provided to support PCIe clocking.
Clock Source | Description |
---|---|
PCIe Edge Connector | 100 MHz clock originating from the PCIe edge connector and connected to
GTY 225 MGTREFCLK0 inputs. The clock signal is AC coupled. |
Internal clock generator | 100 MHz clock originating from the SiTime SiT95145AI clock generator
and connected to GTY 225 MGTREFCLK1 inputs. The clock signal is AC coupled and meets PCIe Gen3/Gen4 jitter specifications. |
