11.10. Optional Status Interface

The following table describes the signals that comprise the optional status interface:

Table 156.  Optional Status Interface 

Signal Name

Direction

Description

rx_is_lockedtodata[<n>-1:0]

Output

When asserted, indicates that the RX CDR is locked to incoming data. This signal is optional. If latency is not critical, you can read the value of this signal from the Rx_is_lockedtodata register.

rx_is_lockedtoref[<n>-1:0]

Output

When asserted, indicates that the RX CDR is locked to the input reference clock. This signal is optional. When the RX CDR is locked to data, you can ignore transitions on this signal. If latency is not critical, you can read the value of this signal from the rx_is_lockedtoref register.

pll_locked[<n>-1:0]

Output

When asserted, indicates that the TX PLL is locked to the input reference clock. This signal is asynchronous.

tx_bitslip[<n>-1:0]

Input

When set, the data sent to the PMA is slipped. The maximum number of bits that can be slipped is equal to the value selected in the serialization factor field - 1 or <d> -1.

rx_bitslip[<n>-1:0]

Input

When set, the RX word aligner operates in bit slip mode.
