Crystal Oscillator Module ICs
OVERVIEW
The SM5005A series are crystal oscillator module ICs, that incorporate high-frequency, low current consump-
tion 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.

FUNCTIONAL DESCRIPTION
Standby Function
The oscillator stops when INH goes LOW. When the oscillator stops, the oscillator output on Q goes high
impedance.
Power-save Pull-up Resistance
The INH pull-up resistance changes in response to the input level (HIGH or LOW). When INH goes LOW
(standby state), the pull-up resistance becomes large to reduce the current consumption during standby.

HIGH (or open) fO output frequency Normal operation

The following figure shows the oscillator timing during normal operation. Note that when the device is in
standby, the oscillator stops. When standby is released, the oscillator starts and stable oscillator output occurs
after a short delay.
