1.3 Device Overview
The TLK110 is a single-port Ethernet PHY for 10Base-T and 100Base TX signaling. It integrates all the
physical-layer functions needed to transmit and receive data on standard twisted-pair cables. This device
supports the standard Media Independent Interface (MII) and Reduced Media Independent Interface
(RMII) for direct connection to a Media Access Controller (MAC).
The TLK110 is designed for power-supply flexibility, and can operate with a single 3.3V power supply or
with combinations of 3.3V and 1.5V power supplies for reduced power operation.
The TLK110 uses mixed-signal processing to perform equalization, data recovery, and error correction to
achieve robust operation over CAT 5 twisted-pair wiring. It not only meets the requirements of IEEE 802.3,
but maintains high margins in terms of cross-talk and alien noise.
