REFERENCE DATA

The data shown in this section is for reference (a metal film resistor and a film capacitor are

used). Resistor and capacitor values must be determined based on experiments.

Use the following expression to convert oscillation frequency to COMMON frame frequency (or

vice versa):

fCOM=fOSC ¥ Duty/16

fCOM : COMMON frame frequency

fOSC : Oscillation frequency

Duty : e.g., 1/4 for 1/4 duty

For example, if fCOM=100Hz at 1/5 duty, the oscillation frequency is fOSC=8000Hz.
