Can I place bonded transceiver channels non-contiguously in Stratix V and Arria GZ transceiver devices?

Description

No, you cannot place bonded transceiver channels non-contiguously in Stratix® V and Arria® V GZ transceiver devices.

For correct operation, bonded channel placement must be contiguous within a transceiver bank.

The following examples show illegal bonded channel configurations.

Example 1: Illegal five channel ATX PLL clocked bonded interface interspersed with an un-bonded channel.

  • GXB_[Tx,Rx]_[L,R][5,11,17,23] = Bonded Interface Channel 1
  • GXB_[Tx,Rx]_[L,R][4,10,16,22] = Bonded Interface Channel 0
  • GXB_[Tx,Rx]_[L,R][3,9,15,21] = Bonded Interface Channel 2
  • GXB_[Tx,Rx]_[L,R][2,8,14,20] = Un-bonded Channel
  • GXB_[Tx,Rx]_[L,R][1,7,13,19] = Bonded Interface Channel 3
  • GXB_[Tx,Rx]_[L,R][0,6,12,18] = Bonded Interface Channel 4

Example 2: Illegal five channel CMU PLL clocked bonded interface intersersed with its own CMU PLL

  • GXB_[Tx,Rx]_[L,R][5,11,17,23] = Channel 4
  • GXB_[Tx,Rx]_[L,R][4,10,16,22] = Used as CMU
  • GXB_[Tx,Rx]_[L,R][3,9,15,21] = Channel 3
  • GXB_[Tx,Rx]_[L,R][2,8,14,20] = Channel 2
  • GXB_[Tx,Rx]_[L,R][1,7,13,19] = Channel 0
  • GXB_[Tx,Rx]_[L,R][0,6,12,18] = Channel 1

You must use an ATX PLL to implement a 5 or 6 channel bonded interface.
