Parameter Range Description
Enable TX data bitslip On/Off When you turn this option On, the TX
gearbox operates in bitslip mode.
Enable RX data polarity inversion On/Off When you turn this option On, the
gearbox inverts the polarity of RX data
allowing you to correct incorrect
placement and routing on the PCB.
Enable RX data bitslip On/Off When you turn this option On, the 10G
PCS RX block synchronizer operates in
bitslip mode.
Enable tx_10g_bitslip port On/Off When you turn this option On, the 10G
PCS includes the tx_10g_bitslip input
port. The data slips 1 bit for every
positive edge of the tx_10g_bitslip
input. The maximum shift is <
pcswidth> -1 bits, so that if the PCS is 64
bits wide, you can shift 0-63 bits.
Enable rx_10g_bitslip port On/Off When you turn this option On, the 10G
PCS includes the rx_10g_bitslip input
port. The data slips 1 bit for every
positive edge of the rx_10g_bitslip
input. he maximum shift is < pcswidth>
-1 bits, so that if the PCS is 64 bits wide,
you can shift 0-63 bits.
PRBS Verifier
You can use the PRBS pattern generators for verification or diagnostics. The pattern generator blocks
support the following patterns:
• Pseudo-random binary sequence (PRBS)
• Pseudo-random pattern
• Square wave
Table 12-35: PRBS Parameters
Parameter Range Description
Enable rx_10g_prbs ports On/Off When you turn this option On, the PCS
includes the rx_10g_prbs_done , rx_10g_
prbs_err and rx_10g_prbs_err_clrsignals
to provide status on PRBS operation.
