Block Diagram
Usage Notes
The oscillator may stop if the power supply rise time is extremely short. To prevent this problem, insert a 500 k
resistor between pin 18 and ground or between pin 21 and ground. (This applies when a crystal oscillator is used.)
This IC should be used with the pin 13 output level between 1 Vp-p and 2 Vp-p.
Use a low-pass filter with a 6-dB attenuation between pins 14 and 16.
Since the high-frequency process is adopted, care must be taken to prevent the influence of static electricity.
