Description
The EM1564 is a very low power crystal oscillator, which
consists of a 32.768 kHz tuning fork crystal and an
advanced CMOS circuit assembled in the same very
small SMD ceramic package.
Very low power consumption, as low as 300nA, is
guaranteed over a very wide supply voltage and
temperature ranges.
The EM1564 is a completely lead free product.
