Description
rx_clkslip[<n>-1:0]
Input
When you turn this signal on, the
deserializer performs a clock slip
operation to achieve word alignment.
The clock slip operation alternates
between skipping 1 serial bit and pausing
the serial clock for 2 cycles to achieve
word alignment. As a result, the period
of the parallel clock can be extended by 2
unit intervals (UI) during the clock slip
operation. This is an optional control
input signal.
Reconfig Interface Ports
reconfig_to_xcvr [(<n>70-1):0]
Input
Reconfiguration signals from the
Transceiver Reconfiguration Controller.
<n> grows linearly with the number of
reconfiguration interfaces.
reconfig_from_xcvr [(<n>46-1):0]
Output
Reconfiguration signals to the
Transceiver Reconfiguration Controller.
<n> grows linearly with the number of
reconfiguration interfaces.
tx_cal_busy[<n>-1:0]
Output
When asserted, indicates that the initial
TX calibration is in progress. It is also
asserted if reconfiguration controller is
reset. It will not be asserted if you
manually re-trigger the calibration IP.
You must hold the channel in reset until
calibration completes.
rx_cal_busy[<n>-1:0]
Output
When asserted, indicates that the initial
RX calibration is in progress. It is also
asserted if reconfiguration controller is
reset. It will not be asserted if you
manually re-trigger the calibration IP.
Table 15-17: Signal Definitions for tx_parallel_data with and without 8B/10B Encoding
The following table shows the signals within
tx_parallel_data
that correspond to data, control, and status
signals for a single 11-bit word.
