IP113M can be a 10/100BASE-TX to 100BASE-FX converter or a 100BASE-FX to 100BASE-FX repeater 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 are designed in DSP approach with advance 0.25um technology; this results in high noise immunity and robust performance.

Besides store and forward mode, IP113M supports modified cut through mode and pure converter mode for low latency data forwarding. IP113M can forward packets up to 1600 bytes to meet requirement of extra long packets.

IP113M supports remote management function. Besides remote monitor and loop back test function defined in TS-1000, IP113M supports remote access functions. Local IP113M can access the MII register of remote IP113M by programming local IP113M's MII registers via SMI. IP113M implements the management function using the maintenance frame defined in TS-1000.

IP113M supports IEEE802.3x, collision base backpressure, and various LED functions, etc. These functions can be configured to fit the different requirements by feeding operation parameters via EEPROM interface or pull up/down resistors on specified pins.
