2. Measurement of oscillating frequencies
When power is turned on, S-35L32A has the internal power-on detecting circuit operating and outputs a
signal of 1 Hz from the INT1 pin to select the crystal oscillator and optimize the Cg value. Turn power on and
measure the signal with a frequency counter following the circuit configuration shown in Figure 25.
Remark
If the error range is
±1 ppm in relation to 1 Hz, time is shifted by approximately 2.6 seconds a
month (as calculated using the following expression)
10
-6 (1ppm) ×60 seconds ×60 minutes ×24 hours × 30 days = 2.592 seconds

Caution 1. Use a high-accuracy frequency counter (1 ppm order).
2. Since the 1 Hz signal continues to be output, you must send the reset command in
normal operation.
3. Determine Cg with its frequency slow/fast range property referred.
