XC2164 Series

ICs for use with Crystal Oscillators

The XC2164 series are high frequency, low current

consumption CMOS ICs with built-in crystal oscillator and

divider circuits.

For fundamental oscillation, output is selectable from any one

of the following values for f0 : f0/1, f0/2, f0/4, f0/8.

With oscillation capacitors and a feedback resistor built-in, it

is possible to configure a stable fundamental oscillator or 3rd

overtone oscillator using only an external crystal.

Also available is an external oscillation capacitor / external

oscillation feedback resistor type which makes oscillation

frequency control possible.

The XC2164 series are integrated into SOT-26 packages.

The series is also available in chip form.
