Notes:
3. Amplifier in limiting mode. Input is a 200MHz square wave.
4. Deterministic jitter measured using 1.25Gbps K28.5 pattern, VID = 10mVpp.
5. Random jitter measured using 1.25Gbps K28.7 pattern, VID = 10mVpp.
6. See “Typical Operating Characteristics” for a graph showing how to choose a particular RSDLVL for a particular SD assert and
its associated de-assert amplitude.
7. This specification defines electrical hysteresis as 20log (SD Assert/SD De-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 optical hysteresis
