GENERAL DESCRIPTIO N
The XC2164 series ar e 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, and 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 externa l crystal. Also the series has stand-by function built-in and the type, which suspends the
oscillation completely (XC2164A~D type) or the type suspends only an output (XC2164K~N type) are available. The XC2164
series are integrated into SOT-26 packages. The series is also ava ilable in chip form.
