General Description
IP1001 is an integrated physical layer device for
1000BASE-T, 100BASE-TX, and 10BASE-T
applications. IP1001 supports MII, GMII and
RGMII for different types of 10/100/1000Mb Media
Access Controller (MAC). It supports Auto
MDI/MDIX function to simplify the network
installation and reduce the system maintenance
cost. IP1001 supports speed down shift feature for
a poor link quality to guarantee data transmission.
Cable analysis function “SCA” is supported by
programming MII registers of IP1001 through
MDC/MDIO.
IP1001 supports 2 types of power saving modes;
i.e., power down mode defined in IEEE802.3, and
APS (auto power saving).

Mode 10Mbps TXD. Synchronous to the
rising edge of GTX_CLK

(10/100M).
Gigabit, The TX_CTL indicates a
RGMII 100Mbps, signal like TX_EN at the
Mode 10Mbps rising edge of TXC. A signal
like TX_ER is derived by the
logical operation of latched
“TX_EN” and the value at the
falling edge of TXC.

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.
