Data Sheet

3 Functional Description

The IP1001 is an Ethernet transceiver for 1000BASE-T, 100BASE-TX, and 10BASE-T. It uses one pair of

UTP wires to transmit data and uses another pair to receive data when working in 100BASE-TX or 10BASE-T.

It uses four pairs of UTP wires to transmit and to receive data when working in 1000BASE-T.

It supports auto-negotiation, including next page exchanging, speed (1000M, 100M, 10M), duplex (full/ half)

mode and master/slave resolution. This device also supports RGMII/ GMII/ MII to interface a MAC device.

Registers in the IP1001 can be accessed via the SMI (MDC/MDIO). Three LEDs shows the various statuses

of the device. Pair skews in the cables are automatically adjusted. Wiring errors are automatically corrected

via pair swapping (automatic MDI/MDIX) and polarity correction.

3.1 Medium Dependent Interface (MDI) for Twisted Pair Cable

The interface between IP1001 and CAT5 cable consists of four signal pairs, channel A, B, C and D, that are

used for 1000BASE-T transmission/receiving. Each signal pair consists of two bi-directional pins that transmit

and receive data stream at the same time.

When the IP1001 operates in 100BASE-TX or 10BASE-T mode, only channel A and B are used, one for

transmission and the other for reception. IP1001 will handle the MDIX/MDI crossover issue of the twisted-pair

wire automatically. Please refer to section 3.5 Auto MDI/MDIX Crossover for detail.
