The calculator converts the clock precision parts per million (PPM) into real-time accuracy expressed in seconds per day or minutes per year.
Input parameters: PPM, seconds/day or minute/year, click the “Calculate” button to get other calculated values.
Input data: error (PPM): 5.8
Click on "Calculate", seconds / day: 0.5; minutes / year: 3.05
Working temperature: 25 ° C
The calculator determines the crystal frequency error (PPM) caused by the crystal temperature characteristics; in addition, the equivalent error value in seconds per day is given.
The frequency error (PPM) produced by the crystal temperature characteristics can be calculated using the formula: -0.042* (25-operating temperature) 2.
