Notes:
4.
Amplifier in limiting mode. Input is a 200MHz square wave.
5.
The time between applying RESET and outputs being disabled.
6.
Deterministic jitter measured using 1.25Gbps K28.5 pattern, VID = 10mVPP.
7.
Random jitter measured using 1.25Gbps K28.7 pattern, VID = 10mVPP.
8.
SD is the opposite polarity of LOS. Therefore, an SD Assert parameter is equivalent to a LOS De-assert parameter and vice versa.
9.
See “Typical Operating Characteristics” for graphs showing input signal vs. SD Assert/LOS De-assert time at various RLOS/SDLVL settings.
10. See “Typical Operating Characteristics” for a graph showing how to choose a particular RLOS/SDLVL for a particular assert and
its associated de-assert amplitude.
11. 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.
12. JAM Low to High transition propagation delay refers to the time it takes from a LOW to HIGH transition at JAM input to turning on (if SD is selected)
or turning off (if LOS is selected) the LVPECL outputs.
13. JAM High to Low transition propagation delay refers to the time it takes from a HIGH to LOW transition at JAM input to turning off (if SD is selected)
or turning on (if LOS is selected) the LVPECL outputs.
