Receive Loss of Signal Indication:

X

0: Normal operation

1: Loss of signal condition detected

Receive Loss of Lock Indication:

This status bit is only defined during a valid input signal at RxP/N or

X

when RXLOS=0

0: Normal operation

1: Recovered receive clock frequency differs from the reference by

more than +/- 100ppm.

X Unused

Transmit Loss of Lock Indication:

This status bit is only defined and valid when using one of the serial

X transmit modes utilizing the Tx CDR.

0: Valid transmit input signal detected at SIxDP/N

1: No valid signal detected at SIxDP/N

Transmit FIFO Error Indication:

This bit is set whenever the internal FERR signal is asserted, indicating

that the FIFO is operating at its depth limit. It is reset to 0 when the

X

FRST pin is asserted.

0: Normal operation

1: Transmit FIFO phase error
