s
Features
8
Compactness and thin (7.8×3.4×1.1 mm).
8
Standard Nominal Frequency for PLL-system are lined up (ex. GSM, PDC, AMPS,
TACS, etc.).
8
Frequency pullability performance which is absolutely required for the purpose of
temperature compensation.
8
Frequency characteristics provides easy making temperature compensation owing to
its stable characteristics closed to crystal fit curve.
8
It is applicable to IR Reflow.
8
Taping package is for customer automatic loading operation.
8
Display of temperature characteristics is possibile using a two-dimensional data code.
