GENERAL DESCRIPTION
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.
