TLK105L (NRND) Industrial temperature, single port 10/100-Mbps Ethernet physical layer

 

Not Recommended for New Designs (NRND)

Replaced By DP83822I – The device has the SAME FUNCTIONALITY and PINOUT as the compared device but is NOT an exact equivalent.
DP83822IF – The device has the SAME FUNCTIONALITY and PINOUT as the compared device but is NOT an exact equivalent. The DP83822IF device is a pin-compatible upgrade of the TLK105 with fiber support.

TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.

Description

The TLK10xL is a single-port Ethernet PHY for 10Base-T and 100Base TX signaling, integrating all the physical-layer functions needed to transmit and receive data on standard twisted-pair cables. The device supports the standard Media Independent Interface (MII) and Reduced Media Independent Interface (RMII) for direct connection to a Media Access Controller (MAC).

The device is designed for power-supply flexibility, and can operate with a single 3.3-V power supply or with combinations of 3.3-V and 1.55-V power supplies for reduced power operation.

The TLK10xL uses mixed-signal processing to perform equalization, data recovery, and error correction to achieve robust operation over CAT 5 twisted-pair wiring. The TLK10xL not only meets the requirements of IEEE 802.3, but maintains high margins in terms of cross-talk and alien noise.

The TLK10xL 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 802.3 100-m cable length, or the extended 150m, error-free cable reach of the TLK10xL. For more detail, see application note SLLA328.
