CDR low-speed recovered clock
■
A high level indicates FIFO is either full or empty.
Values range from 0 to 9.
A high level indicates the CDR is in LTD state.
A low level indicates the CDR is in LTR state.
A high level forces the CDR to LTD state
When deasserted, the receiver CDR lock state depends
on the rx_locktorefclk signal level.
The rx_locktorefclk and rx_locktodata
signals control whether the receiver CDR states as
follows:
[rx_locktodata:rx_locktorefclk]


Available in Basic mode when 8B/10B encoder/decoder
is used, and in PIPE mode.
A high level indicates that the signal present at the
receiver input buffer is above the programmed signal
detection threshold value.
Only available in the GIGE mode for applications such as
Synchronous Ethernet.
2'b00—receiver CDR is in automatic lock mode
2b'01—receiver CDR is in manual lock mode (LTR
state)
2b'1x—receiver CDR is in manual lock mode (LTD
state)
