NIPPON PRECISION CIRCUITS-1

SM5003 Series

Quartz Crystal Oscillator IC

OVERVIEW

The SM5003 Series is quartz crystal oscillator 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
without any external components.

FEATURES

⋅ Oscillation frequency up to 70MHz
⋅ 3rd overtone oscillation
⋅ 4.5 to 5.5 V supply voltage
⋅ Inverter amplifier feedback resistance built-in (Rf )
⋅ Oscillation capacitance built-in (CG and CD)
⋅ Output drive capability : 8 mA (VDD=4.5V)
⋅ Output frequency : fo (Oscillation frequency)

⋅ Output duty level

SM5003A×H : CMOS
SM5003B×H : TTL

⋅ Input level : TTL
⋅ 3 state function
⋅ Chip form (CF5003××)
⋅ 6 pin SOT (SM5003××H)
