■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.
