Function to Clock-Correction
The function to clock-correction is to correct advance/delay of the clock due to the deviation of oscillation frequency, in
order to make a high precise clock. For correction, the S-35192A adjusts the clock pulse by using a certain part of the
dividing circuit, not adjusting the frequency of the crystal oscillator. Correction is performed once every 20 seconds (or 60
seconds). The minimum resolution is approx. 3 ppm (or approx. 1 ppm) and the S-35192A corrects in the range of
195.3
to +192.2 ppm (or of
65.1 to +64.1 ppm). (Refer to Table 11.) Users can set up this function by using the
clock-correction register. Regarding how to calculate the setting data, refer to “1. How to calculate”. When not using this
function, be sure to set “00h”.
