EXTERNAL COMPONENT SELECTION (continued)

Note 1: Nominal crystal load capacitance specifications varies with frequency. Contact

the ICS MicroClock applications department at (408)297-1201

Note 2: The third overtone mode of the crystal and all spurs must be >200 ppm away

from 3x the fundamental resonance shown in the table below.

For recommended crystal devices, please contact the ICS MicroClock application department
