3.1.3. 1G/2.5G/10G MGBASE PCS only

Figure 8. Architecture of the 1G/2.5G/10G MGBASE PCS only configuration
The PCS only mode is supported in the MGBASE 1G/2.5G/10G variant only. For 10M/100M/1G/2.5G ethernet rate, the PCS (including the 8b/10b encoder) is a part of the 1G/2.5G/5G/10G Multirate Ethernet PHY. However, for 10G ethernet rate PCS and 64/66b encoder is a part of the GTS Transceiver PHY.
  • Datapath client-interface:
    • 1G/2.5G—GMII, 16 bits
    • 1G/2.5G/10G—XGMII, 64 bits
Note: PCS only mode is not supported in other MGBASE and NBASE variants.
  • Management interface— Avalon® memory-mapped interface host slave interface for PHY management.
  • Datapath ethernet interface:
    • 10G—Single 10.3125 Gbps serial link
    • 2.5G—Single 3.125 Gbps serial link
    • 10M, 100M, 1G—Single 1.25 Gbps SGMII serial link
