5. Physical Layer Function Description

5.1. MDI Interface

The RTL8309N embeds 8 Fast Ethernet PHYs in one chip. Each port uses a single common MDI

interface to support 10Base-T, 100Base-TX and 100Base-FX. This interface consists of two signal pairs

RXIP/RXIN, and TXOP/TXON. The MDI interface has internal termination resistors for reduced BOM

cost and PCB complexity.
