| Frequency-temperature characteristics of crystal unit (general trend) |
Frequency-temperature deviation and clock error (an indication)
Clock error is around 26 sec when after continued operation in a 10ppm frequency-temperature deviation environment.
[Method of calculation]
1 month (30 days) is converted to 2,592,000 sec.
When frequency-temperature deviation is 10 ppm, clock error is 2,592,000 x 10 x 10^ -6 = 25.92 ≈ 26 sec.
