Physical Layer Transceivers

What are Physical Layer Transceivers?

Ethernet Physical Layer Devices are 10/100 single port physical layer devices that provide several intelligent power down states with reduced power usage. Physical Layer Devices are designed to accommodate a variety of power modes and have a typical low power consumption rating of 270 mW. They use low-power 3.3V, 0.18m CMOS technology. Due to less power dissipation, low power modes improve overall product reliability. To ensure compatibility and interoperability with all other standards-based Ethernet solutions, the integrated sublayers support both 10BASE-T and 100BASE-TX Ethernet protocols.

Through an external Transformer, physical layer devices connect to twisted pair media. Physical Layer Devices are perfect for high-end peripheral devices, industrial controls, factory automation, automotive and transportation, as well as general embedded applications. They have the industry's highest electrostatic discharge (ESD) protection of 4000V, error-free operation up to 150 meters, and a 48-pin LQFP package (7mm x 7mm).

What is the purpose of Physical Layer Transceivers?

The physical layer devices point out the means of transmitting a series of raw binary bits or data over a physical data link through communicating network nodes. The bitstream may be put together into code scripts or symbols and transmitted as a physical layer signal which has been caused through a transmission medium.
