Crystal Oscillator Module ICs
OVERVIEW
The SM5002L series crystal oscillator module ICs fabricated in NPC’s Molybdenum-gate CMOS. They
comprise low-voltage low-current consumption oscillator circuits and output buffers. They incorporate built-in
oscillation capacitance with superior frequency response to realize stable 3rd overtone oscillation without any
external components.
