Gearbox
The gearbox adapts the PMA data width to a wider PCS data width when the PCS is
not two or four times the PMA width.Table 12–30 describes the gearbox parameters.
For more information refer to the Receiver Gearbox section in Transceiver Architecture in
Stratix V Devices.
Table 12–29. Bit Reversal and Polarity Inversion Parameters
Parameter Range Description
Enable RX block synchronizer On/Off
When you turn this option On, the 10G PCS includes the RX block
synchronizer. This option is available for the Interlaken and
10GBASE-R protocols.
Enable rx_10g_blk_lock port On/Off
When you turn this option On, the 10G PCS includes the
rx_10G_blk_lock
output port. This signal is asserted to indicate
the receiver has achieved block synchronization.
This option is available for the Interlaken, 10GBASE-R, and other
protocols that user the PCS lock state machine to achieve and
monitor block synchronization.
Enable rx_10g_blk_sh_err port On/Off
When you turn this option On, the 10G PCS includes the
rx_10G_blk_sh_err
output port. This signal is asserted to
indicate that an invalid sync header has been received. This signal
is active after block lock is achieved.
This option is available for the Interlaken, 10GBASE-R, and other
protocols that user the PCS lock state machine to achieve and
monitor block synchronization.
Table 12–30. Gearbox Parameters (Part 1 of 2)
Parameter Range Description
Enable TX data polarity
inversion
On/Off
When you turn this option On, the gearbox inverts the polarity of
TX data allowing you to correct incorrect placement and routing
on the PCB.
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.
