SM5021

SM5021 series NIPPON PRECISION CIRCUITS INC. Crystal Oscillator Module ICs 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 components to make a stable 3rd-harmonic oscillator.
