Adjustment and measurement methods
DEV adjustment method
Input the reference input (–38 dBm, 1 kHz) to the MIC input and adjust the voltage applied to Pin 36 so
that the Pin 24 output reference frequency deflection is 1.5 MHz ±62.8 kHz.
When adjusting DEV, connect a 10 k
load resistor between Pin 24 and GND.
Reference modulation distortion factor
Demodulate the Pin 24 output into the audio signal with the reference demodulator under the same
conditions as for DEV adjustment above, then measure the distortion factor.
BPF f0 adjustment method
Input 15 mVp-p, 1.4 MHz and 1.6 MHz signals to Pin 22 and adjust the voltage applied to Pin 26 so that
the 1.4 MHz and 1.6 MHz levels output to Pin 23 are equal.
Note that since adjustment OFF mode results when the Pin 26 voltage is between 0 to 0.8 V, the BPF f0
should be adjusted with the Pin 26 voltage between 1.2 to 3 V (when V
CC
1 = 3.15 V). When adjusting the
BPF f0, connect a 4.7 k
load resistor between Pin 23 and GND.
