■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.
