Freq
Designed to meet application
requirements for smaller layout areas.
The CUSO (Crystek Ultra Small
Oscillator) Series utilizes fundamental
and 3rd overtone crystal design
thereby providing the proven
performance of our larger 5x7mm
package. Standby mode and Powersave Pull-up Resistance is standard.
Packaged on tape and reel in
quantities of 1K.
