SM5003 Series
NIPPON PRECISION CIRCUITS INC.
Quartz Crystal Oscillator IC
OVERVIEW
The SM5003 Series is quartz crystal oscillator ICs fabri-
cated 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
without any external components.
