NPC CF5021KE-1 Crystal oscillator module ic Datasheet

SM5021 series
Crystal Oscillator Module ICs
NIPPON PRECISION CIRCUITS INC.
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.
