IP113M/N LF can be a 10/100BASE-TX to 100BASE-FX converter with an SMI port for management. It consists of a 2-port switch controller, a fast Ethernet transceiver and a PHY for 100BASE-FX. The transceivers in IP113M/N LF are designed in DSP approach with advance 0.25um technology; this results in high noise immunity and robust performance.
