EM7604
Low Power Crystal Oscillator 32.768 kHz
Description
The EM7604 is an advanced low power CMOS circuit
intended to be used together with a 32.768 kHz tuning fork
crystal as a low frequency clock oscillator.
Except the crystal, no other external components are
required.
In order to achieve a high frequency accuracy, the matched

as 250nA,
is
guaranteed over a very wide supply voltage and
temperature ranges.
Offered in a small SOT23-6 package, the EM7604 is a
completely lead free product.
Applications
General purpose clock generator for digital systems
Clock drivers for Real Time Clocks
Timekeeping in network servers and computers
Electricity, gas and water metering
