Notes:
7. Amplifier in limiting mode. Input is a 200MHz square wave.
8. Deterministic jitter measured using 4.25Gbps K28.5 pattern, VID = 20mVPP.
9. Random jitter measured using 4.25Gbps K28.7 pattern, VID = 20mVPP.
10. Differential output swing measured at 4.25Gbps with 20mVpp input and PRBS-23 data pattern and 50
load.
11. See “Typical Operating Characteristics” for a graph showing how to choose a particular RLOSLVL for a particular LOS assert and its associated
de-assert amplitude.
12. 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 on the level of received optical power and ROSA characteristics. Based on that
ratio, the optical hysteresis corresponding to the electrical hysteresis range 2dB-4.5 dB shown in the AC characteristics table will be 0.5dB-
3dB Optical Hysteresis.
