Parameter Range Description
Enable rx_seriallpbken port On/Off When you turn this option On, the rx_seriallpbken
is an input to the core. When your drive a 1 on this
input port, the PMA operates in loopback mode with
TX data looped back to the RX channel.
PMA Optional Ports
Table 14-7: RX PMA Parameters
The following table describes the optional ports you can include in your IP Core. The QPI are available to
implement the Intel Quickpath Interconnect.
For more information about the CDR circuitry, refer to the Receiver Clock Data Recovery Unit section in Clock
Networks and PLLs in Arria V GZ Devices.
Parameter Range Description
Enable tx_pma_qpipullup
port (QPI)
On/Off
When you turn this option On, the core includes tx_
pma_qpipullup control input port. This port is only
used for QPI applications.
Enable tx_pma_qpipulldn
port (QPI)
On/Off When you turn this option On, the core includes tx_
pma_qpipulldn control input port. This port is only
used for QPI applications.
Enable tx_pma_txdetectrx
port (QPI)
On/Off When you turn this option On, the core includes tx_
pma_txdetectrx control input port. This port is only
used for QPI applications. 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.
Enable tx_pma_rxfound port
(QPI)
On/Off When you turn this option On, the core includes tx_
pma_rxfound output status port. This port is only
used for QPI applications. The RX detect block in the
TX PMA detects the presence of a receiver at the
other end of the channel. tx_pma_rxfound indicates
the result of detection.
Enable rx_pma_qpipulldn
port (QPI)
On/Off When you turn this option On, the core includes the
rx_pma_qpipulldn port. This port is only used for
QPI applications.
Enable rx_pma_clkout port On/Off When you turn this option On, the RX parallel clock
which is recovered from the serial received data is an
output of the PMA.
Enable rx_is_lockedtodata
port
On/Off When you turn this option On, the rx_is_lockedto-
data port is an output of the PMA.
Enable rx_is_lockedtoref
port
On/Off When you turn this option On, the rx_is_
lockedtoref port is an output of the PMA.
