DS33R11 Ethernet Mapper with Integrated T1/E1/J1 Transceiver

9.15.1 MII Mode Options

The Ethernet interface can be configured for MII operation by setting the hardware pin RMIIMIIS low. The MII interface consists of 17 pins. For instructions on clocking the Ethernet Interface while in MII mode, see Section 9.1. Diagrams of system connections for MII operation are shown in Figure 9-5 and Figure 9-6.

9.15.2 RMII Mode

The Ethernet interface can be configured for RMII operation by setting the hardware pin RMIIMIIS high. RMII interface operates synchronously from the external 50MHz reference (REF_CLK). Only seven signals are required. The following figure shows the RMII architecture. Note that DCE mode is not supported for RMII mode and RMII is valid only for full duplex operation.
