PIN CONFIGURATION
NAME
FUNCTION
NAME
FUNCTION
TXIN+, TXIN–
These differential ECL100K compatible
inputs receive NRZ data from the PHY for
transmission.
TPOUT+,
Outputs from the NRZ buffer drive these
TPOUT–
differential current outputs. The
transmitter filter/transformer module
connects the media to these pins.
LPBK
This TTL input enables transmitter-
Receiver loopback internally when
asserted low.
TXOFF
This TTL input forces the NRZ buffer to a quiet
state when asserted low.
RTSET1,
An external 1% resistor connected
RTSET2
between these pins controls the
transmitter output current amplitude.
IOUT = 64 x 1.25V/RTSET
TVCCA,
Separate analog and digital
TVCCD
transmitter power supply pins help to
isolate sensitive circuitry from noise
generating digital functions. Both supplies
are nominally +5 volts.
TGNDA,
Analog and digital transmitter grounds
TGNDD
provide separate return paths for clean
and noisy signals.
SD+, SD–
These differential ECL100K compatible
outputs indicate the presence of a data
signal with an amplitude exceeding a
preset threshold.
TPIN+, TPIN–
NRZ encoded data from the receiver filter/
transformer module enters the Receiver
through these pins.
PIN DESCRIPTION
RXOUT+,
Differential ECL100K compatible outputs
RXOUT–
provide NRZ encoded data to the PHY.
CAP1, CAP2
Two external capacitors connected to
these pins sets the time constant for the
adaptation in the equalizer loop as well
as for signal detect response.
RRSET1,
Internal time constants controlling the
RRSET2
equalizer’s transfer function are set by an
external resistor connected across these
pins.
CMREF
This pin provides a DC common mode
reference point for the receiver inputs.
RVCCA,
Analog and digital supply pins are
RVCCD
separated to isolate clean and noisy
circuit functions. Both supplies are
nominally +5 volts.
RGND
Receiver ground.
RSET1, RSET2
An external 5k
W resistor across these pins
sets up an internal reference current.
RTH1, RTH2
An external resistor connected across
these pins sets the internal levels for
equalization as well as signal detect. This
resistor allows compensation for transmit
and magnetics variations. RTH should be
set to match the peak-to-peak transmit
amplitude. VAMP = 16 x 1.25 x RTH/RSET
where VAMP is the peak-to-peak
amplitude of the transmit output with
zero length cable.
