General Description
IP113A can be a 10/100BASE-TX to 100BASE-FX
converter or a 100BASE-FX to 100BASE-FX
repeater. 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 0.25-um
technology; this results in high noise immunity and
robust performance.
IP113A not only supports store and forward mode,
it 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.

33 TWO_FIBER
Type
Description
IPL Two fiber ports
1: IP113A supports two-fiber ports mode. Both port 1 and
port 2 are fiber ports. RXIP and RXIM are used as
FXRDP and FXRDM for the second fiber port. TXOP and
TXOM are used as FXTDP and FXTDM for the second
fiber port.
A special requirement for the fiber MAU of port1 in this
application is that the output of FXRDP and FXRDM
should have no incoming signals when fiber wire is
unplugged.
For some fiber MAUs, there are amplified noisy signals
on FXRDP and FXRDM when fiber is unplugged.
These amplified noisy signals, which include coupled
idle patterns from FXTDP and FXTDM will cause the
LEDs of port1 malfunction
Generally, a 3.3-V small form factor type fiber MAUs
(e.g. Agilent HFBR-5903) can meet this special
requirement, but 5-V duplex-SC and -ST type fiber
MAUs cannot. Port2 is not limited by this special
requirement.
0: IP113A supports one fiber port and one TP port. Port 1 is
a TP port and port 2 is a fiber port.
