Frequency-versus-Temperature Characteristics
 
The SC-cut leads the family of doubly-rotated cut crystals in warmup, phase-noise,
G-sensitivity, and aging characteristics. Also, please note from a comparative analysis
with respect to inflection points versus turning-point ranges, the standard SC and IT-cut
graphs compared to the modified SC-cut graphs. As the graphs indicate, frequency and
temperature behaviors differ, which can be advantageous in certain applications.
 
 
 
As a world-leader in doubly-rotated cut crystal technology,
Bliley Technologies has set the standard for innovative design concepts in this field.
