OVERVIEW
The SM5021 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. Highly accurate
thin-film feedback resistors and high-frequency capacitors are built-in, eliminating the need for external com-
ponents to make a stable 3rd overtone oscillator.
