The time taken under stable wave input conditions from when power is applied or standby is released, using PON, until stable digital output occurs within ratings. tON When supply is applied – – 8 sec Startup time (PON)2 tPON From standby mode – – 8 sec Input voltage VIL PON, HLDN – – 0.2 V VIH PON, HLDN VDD – 0.2 – – V Input current IIL VIN = 0V, PON, HLDN −1– – µA IIH VIN = VDD, PON, HLDN – – 1 µA Output voltage VOL IOL = 5µA, OUT – – 0.2 V VOH IOH = − 5µA, OUT VDD – 0.2 – – V Gain hold time tHLD ≤ ± 3dB variation 1 – – sec Fall time output propagation delay3 3. The time taken, with 10:1 input signal amplitude ratio and 500ms pulsewidth, from when a change in signal input occurs until the output OUT changes. Note that this characteristic is very dependent on the antenna and crystal filter characteristics. The standard crystal used here has the fol- lowing equivalent circuit coefficients. tDN FIN = 60kHz, NPC standard crystal, NPC standard jig – – 160 ms Rise time output propagation delay3 tUP – – 200 ms LOW-level output pulsewidth4 (200ms) 4. Values obtained when using the NPC standard crystal employed here. Note that these values are dependent on the crystal characteristics, and should be considered as reference values.
