Parameter Range Description
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.
Enable rx_std_signaldetect port On/Off When you turn this option On, the
optional rx_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
