Notes

34.The TXCLKOx output remains at the character rate regardless of the state of TXRATE and does not follow the duty cycle of REFCLKx±.

35.The rising edge of TXCLKOx output has no direct phase relationship to the REFCLKx± input.

36.TXERRx is synchronous to RXCLKx only when RXCLKx is selected as REFCLK.
