2.6.3.2. Running PCIe* and Non- PCIe* Protocols in a GTS Transceiver Bank

When you configure a GTS transceiver bank to run PCIe* and non- PCIe* protocols, you must use two system PLLs. Since there is only one system PLL in a GTS transceiver bank, a second or third system PLL can be used from the neighboring GTS transceiver banks. For devices with a single transceiver bank, refer to HVIO PLL as System PLL for additional information.

For example, if channels 0 and 1 in GTS transceiver bank 0 are configured for PCIe* , and channels 2 and 3 are configured for Ethernet, then the system PLL in GTS transceiver bank 0 can be configured for PCIe* , and the system PLL from GTS transceiver bank 1 can be configured for Ethernet. The following figure shows the system PLL connections for the example described above.
