TLK111 datasheet

Description :

The TLK111 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.

Additionally, the device supports 100Base-FX signaling via an external optical transceiver. The TLK111 supports the standard Media Independent Interface (MII) and Reduced Media Independent Interface (RMII) for direct connection to a Media Access Controller (MAC).

The IC 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.


1. Programmable Power Back Off to reduce PHY power up to 20% in systems with shorter cables

2. IEEE 1588 SFD indication enables time stamping by a controller or processor

3. Low deterministic latency supports IEEE1588 implementation

4. Cable Diagnostics

5. Programmable Fast Link Down Modes, <10µs reaction time

6. Variable I/O voltage range: 1.8V to 3.3V
