2. General Description
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.
