DP83924BVCE General Description

The DP83924B Quad 10Mbps Ethernet Physical Layer (4TPHY) is a 4-Port Twisted Pair PHYsical Layer Transceiver that includes all the circuitry required to interface four Ethernet Media Access Controllers (MACs) to 10BASE-T. This device is ideally suited for switch hub applications where 8 to 32 ports are commonly used.

The 4TPHY has three dedicated 10Base-T ports. There is an additional port that is selectable for either 10Base-T or for an Attachment Unit Interface (AUI). In 10Base-T mode, any port can be configured to be Half or Full Duplex.

The various modes on the 4TPHY can be configured and controlled via the MII management interface. This manage ment interface makes inter-operability with other manufacturers MAC units relatively easy. If no management interface is desired, most of the critical operating modes of the transceiver can be set via strapping options (latching configuration information during reset). The ENDEC section of the transceiver also supplies a simple Non-Returnto-Zero (NRZ) interface to transmit and receive data to/from standard 10 Mb/s MACs.

The transceivers include on-chip filtered transmit outputs, which reduce emissions and eliminate the need for external filter.

The DP83924BVCE maintains complete hardware and software backwards compatibility with the DP83924AVCE with only a change to one resistor value and disconnecting a second resistor.
