SET0, SET1 (Input for clock pulse frequency setting) pins These pins input the clock pulse frequency setting signals. 4 types of clock pulse frequency can be selected depending on the pin settings. Regarding the combination, refer to "1. Options of clock pulse frequency" in " FOUT Pin Clock Pulse Output". 2. ENBL (Input for clock pulse output control) pin This pin controls the clock pulse output from the FOUT pin. The clock pulse is output from the FOUT pin when the ENBL pin is "H". The FOUT pin is fixed when the ENBL pin is "L". 3. FOUT (Output for clock pulse) pin This pin outputs the clock pulse. Regarding the operation of the clock pulse output, refer to "2. pulse output of FOUT pin " in " FOUT Pin Clock Pulse Output". Also, the FOUT pin output form of Nch open-drain output / CMOS output can be selected. ENBL pin and clock 4. XIN, XOUT (Connection for crystal oscillator) pins Connect a crystal oscillator between the XIN pin and the XOUT pin. 5. VDD (Positive power supply) pin Connect this pin with a positive power supply. Regarding the values of voltage to be applied, refer to " Recommended Operation Conditions". 6. VSS pin Connect this pin to GND. 5 FOR AUTOMOTIVE 125°C OPERA.
