XC2163Series
ETR1403_001
ICs for use with 3rd Overtone Crystal Oscillators
■GENERAL DESCRIPTION
The XC2163 series are high frequency, low current consumption CMOS ICs with built-in crystal oscillator and divider circuits.
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 resistors built-in, it is possible to configure a stable 3rd overtone oscillator using
only an external crystal oscillator.
Also available is an external oscillation capacitor/external oscillation feedback resistor type, which makes oscillation
frequency control possible.
