General Description
IP113A
LF
can
be
a
10/100BASE-TX
to
100BASE-FX converter. It consists of a 2-port
switch controller, a fast Ethernet transceiver and a
PHY for 100BASE-FX. The transceivers in IP113A
LF are designed in DSP approach with advance
0.25-um technology; this results in high noise
immunity and robust performance.
IP113A LF not only supports store and forward
mode, it also supports modified cut through mode
and pure converter mode for low latency data
forwarding. IP113A LF can transmit packet(s) up
to 1600 bytes to meet requirement of extra long
packets.
IP113A LF 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.
