Figure 1. TNETE2004 Architecture

The TNETE2004 provides PHY-interface functions for up to four 10BASE-T half- or full-duplex ports as shown

in Figure 1. The TNETE2004 contains four independent 10BASE-T transceivers in a single chip. Each

transceiver is compliant with IEEE Std 802.3, Section 14, and a compliant management serial-interface port

provides information for network management.

A typical application with external components is shown in Figure 2.
