Notes:
1. Circuit ground is internally isolated from chassis ground.
2. T
is an open collector/drain output, which should be pulled up with a 4.7k – 10k Ohms resistor on
FAULT
the host board. Pull up voltage should be between 2.0V to Vcc + 0.3V. A high output indicates an LED
fault, i.e. LED open or short. Low indicates normal operation. In the low state, the output is pulled to
<0.8V.
3. LED output disabled on T
4. Should be pulled up with 4.7k – 10kohm s on host board to a voltage between 2.0V and 3.6V.
MOD_DEF(0) pulls line low to indicate module is plugged in.
5. LOS is open collector output. Should be pulled up with 4.7k – 10kohms on host board to a voltage
between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.

Notes:
1. Non condensing.
2. Connected directly to TX data input pins. AC coupling from pins into driver IC.
3. We recommend <600mV for best EMI performance.
4. Or open circuit.
5. Into 100 ohms differential termination.
6. 10 – 90 %
7. LOS is an open collector output. Should be pulled up with 4.7k – 10kohms on the host board. Normal
operation is logic 0; loss of signal is logic 1. Maximum pull-up voltage is 5.5V.
8. Receiver sensitivity is compliant with power supply sinusoidal modulation of 20 Hz to 1.5 MHz up to
specified value applied through the recommended power supply filtering network.
9. Peak-to-peak measurement for OC-3 SR-0 or OC-1 SR-0 operation measured with a PRBS 2
pattern.
10. Peak-to-peak measurement based on 4B/5B encoded Fast Ethernet pattern referenced in FDDI PMD
