CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

NOTE:
1. The ICM7213 uses dynamic dividers for high frequency division. As with any dynamic system, information is stored on very small nodal
capacitances instead of latches (static system), therefore there is a lower frequency of operation. Dynamic dividers are used to improve
the high frequency performance while at the same time significantly decreasing power consumption. At low V
SUPPLY
, operation at less
than 1MHz is possible.
