Revision 121904

MK3724

External Capacitor =

2 x (centering error)/(trim sensitivity)

Trim sensitivity is a parameter which can be supplied by

your crystal vendor. If you do not know the value,

assume it is 30 ppm/pF. After any changes, repeat the

measurement to verify that the remaining error is

acceptably low (typically less than ±25 ppm).

Absolute Maximum Ratings

Stresses above the ratings listed below can cause permanent damage to the MK3724. These ratings,

which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of

the device at these or any other conditions above those indicated in the operational sections of the

specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can

affect product reliability. Electrical parameters are guaranteed only over the recommended operating

temperature range.
