■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.

■APPLICATIONS

●Crystal Oscillation Modules

●Computer, DSP Clocks

●Communication Equipment

●Various System Clocks

■PIN CONFIGURATION

■PIN ASSIGNMENT

* Stand-by control pin has a pull-up resistor built-in.
