3.9.1. PMA Bonding

PMA bonding reduces skew between PMA channels. In PMA bonding, only the PMA portion of the transceiver datapath is skew compensated and the PCS is not skew compensated.

In Arria 10 devices, there are two PMA bonding schemes:

  • x6/xN bonding
  • PLL feedback compensation bonding

In either case, the channels in the bonded group need not be placed contiguously.
