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
