2.6.4.9. Design Guidelines

Consider the following guidelines while designing with 1G/10GbE PHY.

Using the 1G/10GbE PHY without the Sequencer

The sequencer brings up channel-based initial datapath and performs parallel detection. To use the 1G/10GbE PHY without the sequencer, turn off the Enable automatic speed detection parameter.

Turning off the sequencer results in the following additional ports:

  • rc_busy
  • start_pcs_reconfig
  • mode_1g_10gbar
These ports perform manual reconfiguration. The following figure shows how these ports are used for 1G and 10G configuration.
