Introduction

The TLK10x is a single-port Ethernet PHY for 10Base-T and 100Base TX signaling. This device integrates

all the physical-layer functions needed to transmit and receive data on standard twisted-pair cables. The

TLK10x supports the standard Media Independent Interface (MII) and Reduced Media Independent

Interface (RMII) for direct connection to a Media Access Controller (MAC).

The TLK10x is designed for power-supply flexibility, and can operate with a single 3.3V power supply or

with combinations of 3.3V and 1.55V power supplies for reduced power operation.

The TLK10x uses mixed-signal processing to perform equalization, data recovery, and error correction to

achieve robust operation over CAT 5 twisted-pair wiring. This device not only meets the requirements of

IEEE 802.3, but maintains high margins in terms of cross-talk and alien noise.

The TLK10x Ethernet PHY has a special Power Back Off mode to conserve power in systems with

relatively short cables. This mode provides the flexibility to reduce system power when the system is not

required to drive the standard IEEE 802.3 100m cable length, or the extended 150m, error-free cable

reach of the TLK10x. For more detail, see application note SLLA328.
