General Description
IP113F 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 IP113F are designed in DSP
approach with advance 0.25um technology; this
results in high noise immunity and robust
performance.
IP113F not only supports store and forward mode,
it also supports modified cut through mode and
pure converter mode for low latency data
forwarding. IP113F can transmit packet(s) up to
1600 bytes to meet requirement of extra long
packets.
IP113F supports remote management function.
IP113F supports remote access functions and it
also supports remote monitor and loop back test
function defined in TS-1000 spec. Local IP113F
can access the MII register of remote IP113F by
programming local IP113F’s MII registers via SMI
connection. IP113F implements the management
function using the maintenance frame defined in
TS-1000 spec.
IP113F 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.

2. Functional Description
Data forwarding
IP113F supports three types of data forwarding mode, store & forward mode, modified cut-through mode
and pure converter mode. It can forward a frame despite of its address and CRC error. IP113F begins to
forward the received data when it receives the frame completely. The latency depends on the packet
length.
Modified cut-through mode
IP113F begins to forward the received data when it receives the first 64 bytes of the frame. The latency is
about 512 bits time width. The maximum packet length is up to1600 bytes in this mode. Please refer to pin
description of FAST_FWD for configuration information.
Pure converter mode
IP113F operates with the minimum latency in this mode. The transmission flow does not wait until entire
frame is ready, but instead it forwards the received data immediately after the data being received. Both
transceivers are interconnected via internal MIIs and the internal switch engine and data buffer are not
used. TP port should be forced at 100M in this application. The packet length is not limited at this mode.
Please refer to pin description of DIRECT_WIRE for configuration information.
Fragment forwarding
IP113F forwards CRC error packets but it will filter fragments when it works in modified cut-through mode.
IP113F forwards fragments if user turns on bit 3 of MII register 20.
TP port force mode
The TP port of IP113F can work at auto mode or force mode. The following table shows all of the
combination of its TP port.
