Notes:
4.
Amplifier in limiting mode. Input is a 200MHz square wave.
5.
Deterministic jitter measured using 1.25Gbps K28.5 pattern, VID = 10mVPP.
6.
Random jitter measured using 1.25Gbps 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-5dB, shown
in the AC characteristics table, will be 1dB-4dB optical Hysteresis.
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.
