2.7.11.1. Master Channel in Bonded Configurations
For PCIe, both the PMA and PCS must be bonded. There is no need to specify the PMA Master Channel because of the separate Master CGB in the hardware. However, you must specify the PCS Master Channel through the Native PHY. You can choose any one of the data channels (part of the bonded group) as the logical PCS Master Channel.
Note: Whichever channel you pick as the PCS master, the fitter selects physical CH1 or CH4 of a transceiver bank as the master channel. This is because the Auto-Speed Negotiation (ASN) block and Master CGB connectivity only exists in the hardware of these two channels of the transceiver bank.
PIPE Configuration | Logical PCS Master Channel # (default) |
---|---|
x1 | 024 |
x2 | 124 |
x4 | 224 |
The following figures show the default configurations:
Figure 67. x2 Configuration
Figure 68. x4 ConfigurationThe figure below shows an alternate way of placing 4 bonded channels. In this case, the logical PCS Master Channel number 2 must be specified as Physical channel 4.
Figure 69. x4 Alternate ConfigurationThe figure below shows an alternate way of placing 4 bonded channels. In this case, the logical PCS Master Channel number 2 must be specified as Physical channel 1.
As indicated in the figures above, the fitter picks either physical CH1 or CH4 as the PCS master in bonded configurations for PIPE.
24 Ensure that the Logical PCS Master Channel aligns with Physical Channel 1 or 4 in a given transceiver bank.
