RSM3
Receive data TTL outputs. RSM 0-
4 output may be sampled
synchronously with RXC’s rising
edge.
Digital ground
Receive data TTL outputs. RSM 0-
4 output may be sampled
synchronously with RXC’s rising
edge.
Digital positive power supply
Receive data TTL outputs. RSM 0-
4 output may be sampled
synchronously with RXC’s rising
edge.
Digital ground
Receive data TTL outputs. RSM 0-
4 output may be sampled
synchronously with RXC’s rising
edge.
Recovered receive symbol clock
TTL output. This 25MHz clock is
phase-aligned with the internal
125MHz bit clock recovered from
the signal received at V
IN+/–
.
Receive data are clocked out at
RSM 0-4 on the falling edges of
this clock.
Digital ground
Signal Detect TTL output. This
output goes high when the signal
at VIN+/- exceeds the preset
amplitude threshold.

DGND1
RSM2
Data quantizer offset-correction
loop, offset-storage capacitor input
pin. The capacitor tied between
this pin and AV
CC
stores the
amplified data quantizer offset
voltage and also sets the dominant
pole in the offset-correction loop.
A 0.1µF surface mount is
recommended.
Data quantizer input bias bypass
capacitor input. The capacitor tied
between this pin and AV
CC
filters
the quantizer’s internal input bias
reference. A 0.1µF surface-mount
capacitor is recommended.
Analog ground
Receive quantizer input. This
differential input pair receives
100BASE-FX NRZI signals from the
network opto-coupler.

Analog positive power supply
Analog positive power supply
Analog positive power supply
Transmit level bias resistor. For
100BASE-FX, an external 2.32kW,
1% resistor connected between
RTSET and AGND3 sets a
precision constant bias current
that gives a nominal output "on"
current of 75mA at I
OUT
.
Analog ground
Transmit LED output. This pin
connects through an external 15W
resistor to AV
CC
when the part is
used to drive a network LED.
