SM5022 series
Crystal Oscillator Module ICs
OVERVIEW
The SM5022 series are crystal oscillator module ICs fabricated in NPC’s Molybdenum-gate CMOS, that
incorporate high-frequency, low current consumption oscillator and output buffer circuits. Feedback resistors
and high-frequency capacitors are built-in, eliminating the need for external components to make a stable fun-
damental oscillator.

*1. Chip form devices have designation CF5022××.
*2. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscilla-
tor frequency band is not guaranteed. Specifically, the characteristics can vary greatly due to crystal characteristics and mounting conditions, so the
oscillation characteristics of components must be carefully evaluated.
