General Description :

IP113A 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 IP113A are designed in DSP approach with advance 0.25um technology; this results in high noise immunity and robust performance.

IP113A not only supports store and forward mode, IP113A also supports modified cut through mode and pure converter mode for low latency data forwarding. IP113A can transmit packet(s) up to 1600 bytes to meet requirement of extra long packets.

IP113A 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.
