Connected directly to TX data input pins. AC coupling from pins into laser driver IC. We recommend <600 mV for best EMI performance. Or open circuit. Into 100 ohm differential termination. 20 – 80 % LOS is an open collector output. Should be pulled up with 4.7 k - 10 kohms on the host board. Normal operation is logic 0; loss of signal is logic 1. Maximum pull-up voltage is 5.5 V. Receiver sensitivity is compliant with a power supply sinusoidal modulation of 20 Hz to 1.5 MHz up to specified value applied through the recommended power supply filtering network. Typical peak-to-peak jitter (=6*RMS width of Jitter). Measured with DJ-free data input signal.
