5026 series
Crystal Oscillator Module ICs
OVERVIEW
The 5026 series are miniature crystal oscillator module ICs. They feature a damping resistor R
D
matched to the
crystal's characteristics to reduce crystal current. They support fundamental oscillation and 3rd overtone oscil-
lation modes. The 5026 series can be used to correspond to wide range of applications.

*1. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscil-
lator 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.
*2. The CF5026BL1 has a higher maximum operating frequency, hence the negative resistance is also larger than in the CF5026AL
