contents 1. test circuit 1 2. temperature characteristics of oscillating frequency, oscillating voltage 2 3. rise time, oscillating frequency, oscillating voltage vs vcc characteristics 3 note : rise time ''rise time" is defined as the time when oscillation voltage reaches 90% of full voltage swing after vdd(vset) is supplied. in the case that rising time of vdd(vset) is slow comparing to resonator's rise time due to the bypass capacitor, resonator's rise time is also slow because it depends on rising time of vdd(vset). also, in the case that the time supplying voltage to the oscillator circuit takes a certain time by reset time etc after vdd(vset) is applied, resonator's rise time is also slow. in these case, we will describe "unable to measure" in rise time data, because we can not measure resonator's rise time correctly. murata manufacturing co., ltd. tcd-06-0170
