Adjustment of Oscillating Frequency
1.
Configuration of the oscillating circuit
Since crystal oscillation is sensitive to external noises (clock accuracy is affected), the fallowing measures must be taken in configuring
the oscillating circuit:
(1) S-3530A, crystal oscillator and external capacitor (Cg) are placed as close to each other as possible.
(2) Make high the insulation resistance between terminals and the board between XIN and XOUT.
(3) Do not place any signal or power lines close to the oscillating circuit.

Note 1: Use a high-accuracy frequency
counter (1ppm order).
Note 2: Since the 1HZ 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.

Measurement of oscillating frequencies
When power is turned on, S-3530A has the internal power-on detecting circuit operating and outputs a signal of 1HZ from the INT1
terminal 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 22. Refer to 11 and 14 pages in this document for further information.
(*) If the error range is ±1ppm in relation to 1HZ, time is shifted by approximately 2.6 seconds a month:
