Notes:
6. Amplifier in limiting mode. Input is a 200MHz square wave.
7. Deterministic jitter measured using 10 Gbps K28.5 pattern, V
8. Random jitter measured using 10Gbps K28.7 pattern, V
9. See “Typical Operating Characteristics” for a graph showing how to choose a particular R
10. This specification defines electrical hysteresis as 20log (LOS De-Assert/LOS Assert). The ratio between optical hysteresis and electrical

hysteresis is found to vary between 1.5 and 2 depending upon the level of received optical power and ROSA characteristics. Based on that ratio,
the optical hysteresis corresponding to the electrical hysteresis range 1dB-4.5 dB, shown in the AC characteristics table, will be 0.5dB-3dB

consecutive identical bits in the application (typical values are in the range of 0.001µF to 1.0µF).
