ICs for use with 3rd Overtone Crystal Oscillators

Series

1031

14

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.
