2004-06-23
The Infineon iSFPTM multimode transceiver is a single unit comprised of a transmitter, a
receiver, and an LCTM receptacle.
This transceiver supports the LCTM connectorization concept. It is compatible with RJ-45
style backpanels for high end datacom and telecom applications while providing the
advantages of fiber optic technology.
The module is designed for low cost SAN, LAN, Fibre Channel and Gigabit Ethernet
applications. It can be used as the network end device interface in mainframes,
workstations, servers, and storage devices, and in a broad range of network devices
such as bridges, routers, hubs, and local and wide area switches.
This transceiver operates at 1.0625 Gbit/s / 1.25 Gbit/s / 2.125 Gbit/s from a single power
supply (+3.3 V). The 100
differential data inputs and outputs are LVPECL and CML
compatible.
Functional Description of iSFPTM Transceiver
This transceiver is designed to transmit serial data via multimode cable.
