Notes:
1. Non condensing.
2. Connected directly to TX data input pins. AC coupling from pins into laser driver IC.
3. We recommend <600mV for best EMI performance.
4. Or open circuit.
5. Into 100 ohms differential termination.
6. Unfiltered, 20 – 80 %
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. Typical peak-to-peak jitter (=6*RMS width of Jitter).
10. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ
and
Δ DJ. If measured with TJ-free data input signal. In actual application, output TJ will be given by:
