Measurement of oscillating frequencies
When power is turned on, S-3531A 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 21.
(*) If the error range is
±1ppm in relation to 1 Hz, time is shifted by approximately 2.6 seconds a
month:

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

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