Requires external regulation and supply decoupling. (22 uF, 330 pF)
3.0
3db loop response.
4.0
50-ohm load biased to 1.3 volts.
5.0
Entry into Free Run doesn’t meet requirement for initial 2.33 seconds of self-timing.
6.0
If the selected reference is removed system response to the ALARM must be less than 100ns.
