6.2 Ethernet Interfaces Signal Description
The 4450 is normally located in a system between a copper or fiber PHY and a Host's
GMAC. The network side of the 4450 functions like a MAC device and the host side
functions like a PHY. The host side interface provides six separate electrical signalling
options which include: GMII/TBI, RGMII/RTBI, SGMII, and SERDES. For the network side
interfaces, only RGMII/RTBI, SGMII and SERDES signalling options are available. GMII/TBI
signalling is not supported on the network side. The GMAC interfaces are capable of running
at 10/100/1000 speeds in either the GMII, RGMII or SGMII modes. The TBI, RTBI and
SERDES interfaces only support 1 Gbps speeds and will not run at 10/100 speeds. Note that
the 4450 is not designed to operate in asymmetric rate scenarios where for example the
host side is running at 1 Gbps and the network side at 10 Mbps.
Three configuration pins, host_config[2:0] are provided to select one of eight operating
configurations for the Host GMAC interfaces. The net_config[1:0] pins select one of four
details on the GMAC Interface configurations.
6.2.1
GMAC GMII/TBI Interface Usage (Host-side Only)
This section discusses the use of the Host Side GMAC interfaces h0 and h1 when configured
to support operation in GMII or TBI modes.
