Notes:
4. Amplifier in limiting mode. Input is a 200MHz square wave.
5. Deterministic jitter measured using 3.2Gbps K28.5 pattern, VID = 10mVPP.
6. Random jitter measured using 3.2Gbps K28.7 pattern, VID = 10mVPP.
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 upon that ratio, the optical hysteresis corresponding to the electrical hysteresis range 2dB-4.5dB, as
shown in the AC characteristics table, will be 1dB-3dB.
8. 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.
