Notes:
7. Amplifier in limiting mode. Input is a 200MHz square wave, t
r < 300ps.
8. Deterministic jitter measured using 2.488Gbps K28.5 pattern, V
ID = 10mVPP. Random jitter measured using 2.488Gbps K28.7 pattern, VID = 10mVPP.
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
LOSLVL 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.
