GENERAL DESCRIPTION

The XC2164 series are high frequency, low current

consumption CMOS ICs with built-in crystal oscillator and

divider circuits.

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 the

series has stand-by function built-in and the type, which

suspends the oscillation completely (C/E type) or the type

suspends only an output (O/E type) are available. The

XC2164 series are integrated into SOT-26 packages. The

series is also available in chip form.
