XC2164 Series CMOS Low Power Consumption Oscillation Frequency 4MHz to 125MHz 4MHz to 30MHz (Fundamental Oscillation) 20MHz to 125MHz (3rd Overtone Oscillation) 3 State Output Built-in Capacitors Cg, Cd Built-in Feedback Resistor Chip form Mini Mold SOT-26 Package 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.
