EM7604-C7- Oscillators

Ultra-low power clock oscillator module

General Description

The EM7604-C7 is an ultra-low power 32.768kHz clock oscillator module. The ultra-low power CMOS oscillator circuit EM7604 and a 32.768 kHz tuning fork crystal are assembled in the ultra-miniature SMT C7 ceramic package.

It has an excellent oscillator stability over a wide voltage and temperature range. No other external components are required.

Besides the standard temperature range between -10°C to +85°C.

The EM7604-C7 can replace a standard crystal and a standard CMOS oscillator circuit.  It has a very small footprint and package height and is therefore optimal suited for miniaturized applications.
