Parameter Range Description
Enable rx_std_bitrev_ena port On/Off When you turn this option On, asserting rx_
std_bitrev_ena control port causes the RX
data order to be reversed from the normal
order, LSB to MSB, to the opposite, MSB to
LSB. This signal is an asynchronous input.
Enable rx_std_byterev_ena port On/Off When you turn this option On, asserting rx_
std_byterev_ena input control port causes
swaps the order of the individual 8- or 10-bit
words received from the PMA.
Enable tx_std_polinv port On/Off When you turn this option On, the tx_std_
polinv input is enabled. You can use this
control port to swap the positive and negative
signals of a serial differential link if they were
erroneously swapped during board layout.
Enable rx_std_polinv port On/Off When you turn this option On, the rx_std_
polinv input is enabled. You can use this
control port to swap the positive and negative
signals of a serial differential link if they were
erroneously swapped during board layout.
Enable tx_std_elecidle port On/Off When you turn this option On, the tx_std_
elecidle input port is enabled. When this
signal is asserted, it forces the transmitter to
electrical idle. This signal is required for the
PCI Express protocol.
Enable rx_std_signaldetect port On/Off When you turn this option On, the optional
tx_std_signaldetect output port is
enabled. This signal is required for the PCI
Express protocol. If enabled, the signal
threshold detection circuitry senses whether
the signal level present at the RX input buffer
is above the signal detect threshold voltage
that you specified.
For SATA / SAS applications, enable this port
and set the following QSF assignments to the
transceiver receiver pin:
set_instance_assignment -name XCVR_
RX_SD_ENABLE ON
set_instance_assignment -name XCVR_
RX_SD_THRESHOLD 7
set_instance_assignment -name XCVR_
RX_COMMON_MODE_VOLTAGE VTT_OP55V
set_instance_assignment -name XCVR_
RX_SD_OFF 1
set_instance_assignment -name XCVR_
RX_SD_ON 2
