Functional Description
3.1
Introduction
As a fully integrated IEEE 802.3 compliant repeater capable of 10 Mbps and 100 Mbps operation,
the LXT98x3 is a versatile device allowing great flexibility in Ethernet design solutions.
Figure 3
shows a typical application. Refer to
"Application Information”

PD
Redundant Power Supply Present.
Active High input indicates presence of
redundant power supply. Tie Low if not used.

RPS_FAULT
I
PU
Redundant Power Supply Fault. Active Low input indicates redundant power
supply fault. The state of this input is reflected in the RPS_LED output (refer to
LED section). Tie High if not used.

RESET
I
Schmitt
Reset.
This active Low input causes internal circuits, state machines and
counters to reset (address tracking registers do not reset). On power-up,
devices should not be brought out of reset until the power supply stabilizes to
3.3V. When there are multiple devices, it is recommended all be supplied by
a common reset driven by an
‘
LS14 or similar device.

First Position Select.
In multi-chip configurations, this pin identifies one
device on each board that drives the HOLDCOL signal to extend non-local
collisions to other devices on the board. Set Low for first device on the PCB.
Set High for all other devices on the PCB.
