1. Measured using the standard circuit.
2. 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.
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.
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.
5. Time averaged rms values, where the noise is white noise and the measurement bandwidth is determined by the crystal filter equivalent used in the
standard circuit.
