Notes:

7. Amplifier in limiting mode. Input is a 200MHz square wave, t

8. Deterministic jitter measured using 2.488Gbps K28.5 pattern, V

9. Electrical signal.

10. This is the detectable range of input amplitudes that can assert LOS. The input amplitude to deassert LOS is 2–8dB higher than the assert ampli-

tude. See “Typical Operating Characteristics” for graphs showing how to choose a particular V

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.
