描述 Description

IP113S LF built in a 3-port switch controller, an OAM engine, a fast Ethernet transceiver, a PHY for 100BASE-FX and three MII I/F. Two of these MII can be configured as SMII I/F. The powerful switch engine supports flow control, VLAN, CoS , port mirroring, and trunking, etc. The transceivers in IP113S LF are designed in DSP approach with advance 0.25um technology; this results in high noise immunity and robust performance.

IP113S LF can be a 10/100BASE-TX to 100BASE-FX converter with an MII to connect to an external PHY for back up fiber application or an external MAC for web management application. IP113S LF forwards packets with length up to 2046 bytes in store and forward mode and modified cut through mode and it can support jumbo frame (up to 9K bytes) in pass through mode and converter mode and auto converter mode to meet requirement of extra long packets.

IP113S LF supports remote access function and loop back test function defined in TS-1000 standard version 2 (*). Local IP113S LF can access the registers of remote IP113S LF by programming local IP113S LF’s registers via SMI connection. IP113S LF implements the management function using the maintenance frame defined in TS-1000 spec.

IP113S LF supports SMII to connect to a switch controller to build up a multiple-port fiber switch, which supports TS-1000. IP113S LF is a two-port 100BASE-FX PHY with TS-1000 function in this application.
