IXP42X Product Line of Network Processors and IXC1100 Control Plane Processor
Console UART Interface
MII Interface
The IXP42X product line and IXC1100 control plane processors have two integrated 10/
100-Mbps MAC with two industry-standard Media Independent Interfaces (MII), except
for the IXP422, which has only one MII. The processors include a single Management
Data Interface – Management Data Input Output (MDIO) and Management Data Clock
(MDC). The MII interfaces and the single management data interface are used to
communicate, control, and configure PHY devices.

processors’ MII port. Rates of 25 MHz for 100-Mbps operation or 2.5 MHz 10-Mbps
operation clocks for TX and RX MII interface (ETH_TX_CLK, ETH_RX_CLK) for each
Ethernet PHY are expected to be supplied from onboard oscillators or PLL.
