Measurement of oscillation frequency
When the S-35192A is turned on, a signal of 32.768 Hz is output from the 32KO pin. Turn the power on and measure the
signal with a frequency counter following the circuit configuration shown in Figure 37.
Remark
If the error range is
±1 ppm in relation to 32.768 kHz, the time is shifted by approximately 2.6 seconds per
month (calculated using the following expression).

–6 (1 ppm) × 60 seconds × 60 minutes × 24 hours × 30 days = 2.592 seconds
