Notes:
8. Amplifier in limiting mode. Input is a 200MHz square wave, tr < 300ps.
9. Deterministic jitter measured using 2.488Gbps K28.5 pattern, VID = 10mVPP. Random jitter measured using 2.488Gbps K28.7 pattern, VID = 10mVPP.
10. Electrical signal.
11. This is the detectable range of input amplitudes that can assert LOS. The input amplitude to de-assert LOS is 2–8dB higher than the assert
amplitude. See “Typical Operating Characteristics” for graphs showing how to choose a particular VLOSLVL or RLOSLVL for a particular LOS assert,
and its associated de-assert, amplitude. If increased LOS sensitivity and hysteresis are required, an application note entitled “Notes on Sensitivity
and Hysteresis in Micrel Post Amplifiers” is available at http://www.micrel.com/product-info/app_hints+notes.shtml.
