“Oscillation start up time” means the period that the oscillation start moves from a transient state when the IC is activated. Murata defines as the time to reach 90% of the oscillation level under steady state conditions.
“Oscillation start up time” is primarily a function of the oscillation circuit design.
Generally “Oscillation start up time” of CERALOCK®
is more than 10 times faster than conventional crystal.
