SM5023 series
Miniature-package Crystal Oscillator Module ICs
OVERVIEW
The SM5023 series are 3rd overtone crystal oscillator module ICs. They feature built-in oscillator capacitors
with excellent frequency response. As cutoff frequency can be configured by using an external feedback resis-
tor Rfo, a favorable 3rd overtone oscillation can be realized with a few external components. The oscillator cir-
cuit characteristics are optimized for a 3rd overtone oscillation by round blank. They also feature a built-in
output buffer with high output drive capability and are available in miniature 6-pin package, making them ideal
as DIP-type crystal oscillators.

1. The 3rd overtone frequency range using an external resistor to set the cutoff frequency. The recommended operating frequency is a yardstick value
derived from the crystal used for NPC characteristics authentication. However, the oscillator frequency band is not guaranteed. Specifically, the char-
acteristics can vary greatly due to crystal characteristics and mounting conditions, so the oscillation characteristics of components must be carefully
evaluated.
