ꢁ GENERAL DESCRIPTION
ꢁ FEATURES
The XC2164 series are high frequency, low current
consumption CMOS ICs with built-in crystal oscillator and
divider circuits.
Oscillation Frequency:
Divider Ratio:
Output:
4MHz to 30MHz (Fundamental)
20MHz to 125MHz (3rd Overtone)
Selectable from f0/1, f0/2, f0/4, f0/8.
( f0/2, f0/4, f0/8 are fundamental only)
3-State
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.
Operating Voltage Range: 3.3V ± 10%, 5.0V ± 10%
Low Power Consumption: Stand -by function included
Selectable from C/E type and O/E type
Chip Size 1.3 × 0.8 mm
SOT-26 mini mold
Chip Form:
The XC2164 series are integrated into SOT-26 packages.
The series is also available in chip form.
