General Description

DAVICOM’s DM9161C is a physical layer, low power, and single-chip 10BASE-T/100BASE-TX

transceiver specifically designed for consumer electronics, industrial, and enterprise applications. Through using a CMOS process, the DM9161C has the advantage of ensuring both high performance and savings in power consumption.

Features

Fully complies with IEEE 802.3 / IEEE802.3u 10Base-T/ 100Base-TX, ANSI X3T12 TP-PMD 1995 standards

Support HP MDI/MDI-X auto crossover function (HP Auto-MDIX)

Support Auto-Negotiation function, compliant with IEEE 802.3u

Fully integrated Physical layer transceiver On-chip filtering with direct interface to magnetic transformer

Selectable repeater or node mode

Selectable MII or RMII (Reduced MII) mode for 100Base-TX and 10Base-TX. Selectable MII or GPSI (7-Wired) mode for 10Base-T

Selectable full-duplex or half-duplex operation

MII management interface with mask-able interrupt output capability
