The XR3085XED-F is a monolithic transceiver that interfaces the physical layer of Local Area Networks (LANs) to their media, in accordance with the Ethernet protocol. This device integrates both a physical layer driver and a physical layer receiver and is built using advanced CMOS technology. The XR3085XED-F is designed for systems and networks utilizing 10-Mb/s Ethernet networks, usually within a range of 100m.

Application Field

The most common application field of the XR3085XED-F is in the Local Area Network (LAN) communication system. It allows the transfer of data between computers that are present within a single building, or a relatively short-range area. It is also found in switches, routers, storage devices, and other networking equipment, ensuring that data can be transmitted reliably and quickly, even at high speed.

The main advantage of this transceiver is its high speed and reliability. The XR3085XED-F can support data transfers at a rate of 10-Mb/s, which is approximately 10x faster than a 10-Mb/s ethernet connection. This device can also be easily integrated into the network due to its auto-negotiation and auto-parity capabilities.

Besides the Local Area Network, the XR3085XED-F can also be used for applications in voice over IP (VoIP), as it provides support for dual-line devices, such as digital PBXs, and is capable of transmitting both voice and data over the same network.

Working Principle

The XR3085XED-F is an ISo/IEC-compliant transceiver that is optimized to support the hybrid fiber/copper local area network (LAN) environment. It is designed to provide good interoperability, tolerance to common mode noise, and compatibility with a variety of LAN standards and protocols. The device is compliant with the IEEE 802.3-1997 standard and provides all of the necessary functions and features for transmission/reception over media up to 100 meters. It also offers full-duplex, 10-Mb/s Ethernet data transfer.

The principle behind the operation of the XR3085XED-F is based on the 4B/5B encoding scheme, which is used to represent data in the encoded form for improved LAN performance. The 4B/5B encoding scheme enables the device to transmit and receive data without encountering any errors caused by noise. It also reduces the overhead associated with data coding and transmission, thus improving the overall performance of the system.

The XR3085XED-F transceiver also provides integrated physical layer management functions, such as IEEE 802.3-1997 auto-negotiation and auto-parity, link diagnostics, and link heartbeat. This device supports full-duplex operation and supports both Manchester-encoded line codes and timeslot codes. The XR3085XED-F data rate is up to 10 Mb/s and is compatible with the standard 10-Mb/s Ethernet frame-based protocol.

The XR3085XED-F transceiver provides excellent EMC protection and is suitable for operating temperatures from 0°C to 70°C. Its excellent timing accuracy and minimum propagation delay further ensure an optimal working environment for systems and networks utilizing 10-Mb/s Ethernet networks.
