Texas Instruments PHYTER® 10/100 Ethernet Physical Layer Transceiver

Texas Instruments PHYTER® 10/100 Ethernet Physical Layer Transceivers are 10/100 single port physical layer devices offering low power consumption with several intelligent power down states. Designed to support multiple power modes using low-power 3.3V, 0.18μm CMOS technology, TI PHYTER 10/100 Ethernet Physical Layer Transceivers have a typical low power consumption rating of < 270mW. The low power modes increase overall product reliability due to decreased power dissipation. The integrated sublayers support both 10BASE-T and 100BASE-TX Ethernet protocols to enable compatibility and interoperability with all other standards-based Ethernet solutions. 

The PHYTER® 10/100 Ethernet Physical Layer Transceivers interface to twisted pair media via an external transformer. With the industry's highest electrostatic discharge (ESD) protection of 4000V, error-free operation up to 150 meters, space-saving 48-pin LQFP package (7mm) x (7mm), and IEEE 802.3 specification compliance, the PHYTER® 10/100 Ethernet Physical Layer Transceivers are ideally suited for high-end peripheral devices, industrial controls and factory automation, automotive and transportation, and general embedded applications.
