The 5026 series are miniature crystal oscillator module ICs. They feature a damping resistor RD matched to the crystal's characteristics to reduce crystal current. They support fundamental oscillation and 3rd overtone oscillation modes. The 5026 series can be used to correspond to wide range of applications.
