Clock operation
M41T82 M41T83
The on-chip capacitance can be calculated as follows:
For example:
●
CLOAD (12h = x0000000) = 12.5 pF,
●
CLOAD (12h =11001000) = 3.5 pF, and
●
CLOAD (12h = 00100111) = 17.4 pF.
The oscillator sees a minimum of 3.5 pF with no programmable load capacitance selected.
Note:
These are typical values, and the total load capacitance seen by the crystal will include
approximately 1-2 pF of package and board capacitance in addition to the Analog
Calibration register value.
Any invalid value of Analog Calibration will result in the default capacitance of 25 pF.
The combination of analog and digital trimming can give up to –93 to +156 ppm of the total
adjustment.
Figure 18 on page 33 represents a typical curve of clock ppm adjustment versus the Analog
Calibration value. This curve may vary with different crystals, so it is good practice to
evaluate the crystal to be used with an M41T8x device before establishing the adjustment
values for the application in question.
