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.
