tx_pma_txdetectrx
Input
When asserted, the RX detect block in the TX PMA detects the
presence of a receiver at the other end of the channel. After
receiving a
tx_pma_txdetectrx
request, the receiver detect
block initiates the detection process. Only for QPI applications.
tx_pma_rxfound
Output
Indicates the status of an RX detection in the TX PMA. Only for
QPI applications.
rx_pma_qpipulldn
Input QPI control input port. Only for QPI applications.
TX and RX serial ports
tx_serial_data[<n>-1:0]
Output TX differential serial output data.
rx_serial_data[<n>-1:0]
Input RX differential serial output data.
Control and Status ports
rx_seriallpbken[<n>-1:0]
Input
When asserted, the transceiver enters loopback mode. Loopback
drives TX data to the RX interface.
rx_set_locktodata[<n>-1:0]
Input
When asserted, programs the RX CDR to manual lock to data
mode in which you control the reset sequence using the
rx_setlocktoref
and
rx_setlocktodata
. Refer to Reset
Sequence for CDR in Manual Lock Mode inTransceiver Reset
Control and Power-Down in Arria V Devices for more information
about manual control of the reset sequence.
rx_set_locktoref[<n>-1:0]
Input
When asserted, programs the RX CDR to manual lock to
reference mode in which you control the reset sequence using the
rx_setlocktoref
and
rx_setlocktodata
. Refer to Reset
Sequence for CDR in Manual Lock Mode in Transceiver Reset
Control and Power-Down in Arria V Devices for more information
about manual control of the reset sequence.
pll_locked[<p>-1:0]
Output
When asserted, indicates that the PLL is locked to the input
reference clock.
rx_is_lockedtodata[<n>-1:0]
Output When asserted, the CDR is locked to the incoming data.
rx_is_lockedtoref[<n>-1:0]
Output
When asserted, the CDR is locked to the incoming reference
clock.
rx_clkslip[<n>-1:0]
Input
When asserted, the deserializer slips one clock edge. This signal
is used to achieve word alignment.
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 Reconfiguration status, indicates TX calibration is in progress
rx_cal_busy[<n>-1:0]
Output Reconfiguration status, indicates RX calibration is in progress
