description

The TNETE2101 physical-layer (PHY) device from Texas Instruments (TI

™) is a single-chip, high-performance

solution for a range of 10BASE-T, 100BASE-TX, and 100BASE-FX networking systems (see Figure 1). The

highly integrated TNETE2101 includes an on-board media-independent interface (MII) for simple connection

to IEEE Std 802.3-compliant media-access controls (MACs). The device integrates all filtering and rise-time

control functions for a cost-effective and space-saving PHY solution. Built-in autonegotiation allows automatic

selection of half-/full-duplex 10BASE-T or 100BASE-TX, with an autopolarity-correction feature for immunity

to receive-pair reversal.
