TX scrambler seed User‑specified 15-bit value You must provide a different seed for each lane. This parameter is only required for the Interlaken protocol.

Interlaken Disparity Generator and Checker

The Disparity Generator monitors the data transmitted to ensure that the running disparity remains within a ±96-bit bound. It adds the 67th bit to indicate whether or not the data is inverted. The Disparity Checker monitors the status of the 67th bit of the incoming word to determine whether or not to invert bits[63:0] of the received word. The following table describes Interlaken disparity generator and checker parameters.

Table 281.  Interlaken Disparity Generator and Checker Parameters
Parameter Range Description
Enable Interlaken TX disparity generator On/Off When you turn this option On, the 10G PCS includes the disparity generator. This option is available for the Interlaken protocol.
Enable Interlaken RX disparity generator On/Off When you turn this option On, the 10G PCS includes the disparity checker. This option is available for the Interlaken protocol.

Block Synchronization

The block synchronizer determines the block boundary of a 66-bit word for the 10GBASE-R protocol or a 67-bit word for the Interlaken protocol. The incoming data stream is slipped one bit at a time until a valid synchronization header (bits 65 and 66) is detected in the received data stream. After the predefined number of synchronization headers is detected, the block synchronizer asserts rx_10g_blk_lock to other receiver PCS blocks down the receiver datapath and to the FPGA fabric. The block synchronizer is designed in accordance with both the Interlaken protocol specification and the 10GBASE-R protocol specification as described in IEEE 802.3-2008 Clause-49.

Table 282.  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.

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 283.  Gearbox Parameters
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.
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
