The elastic buffer in the device-specific transceiver can be used reliably when the following conditions are met:

  • 10 Mbps operation is not required. Both 1 Gbps and 100 Mbps operation can be guaranteed.
  • When the clocks are closely related (see Closely Related Clock Sources).

If there is any doubt, select the FPGA logic receive elastic buffer implementation.
