43 / 444 page  Functional Descriptions VMDS-10492 VSC7440 Datasheet Revision 4.2 26 3.4.2 Dual-Media Mode Ports 0 and 1 are dual-media ports and support either a 1G copper transceiver or a 1G SERDES interface. The dual-media mode is configurable per port through DEVCPU_GCB::PHY_CFG.PHY_ENA. 3.4.3 10G Modes The two 10G ports can be used in two different modes: • SFI mode The 10G port connects to a SERDES10G macro through a DEV10G port module enabling 10G SFI. • 1G/2.5G mode The 10G port connects to a SERDES10G macro through a DEV2G5 port module enabling 1G and 2.5G port speeds. The 10G modes are configurable per 10G port through HSIO::HW_CFG. The following illustration shows an overview of the I/O muxing, associated port modules, and SERDES macros for the 10G ports. 10GBASE-KR IEEE 802.3, Clause 72 10G 1 x 10.3125 Gbps PCB, backplane 64B66B x SFP+(SFI) SFF-8431: Direct Attached Cu IEEE 802.3, Clause 52 - LAN 10G 1 x 10.3125 Gbps 1 x 10.3125 Gbps SFP+ PCB, cable 64B66B x 1. This column applies to SERDES6G ports, as well as SERDES10G_0 and SERDES10G_1.
