XC2165
Series
ICs for use with low voltage Crystal Oscillators
ETR1407_001
Preliminary
■GENERAL
DESCRIPTION
The XC2165 series are CMOS ICs operates from supply voltage range from 1.5V to 3.6V 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 resistor built-in, it is possible to configure a stable fundamental oscillator using only
an external crystal.
In stand-by mode, oscillation stops completely and output pin Q0 becomes in the state of high impedance.
The XC2165 series are integrated into SOT-26 packages.
The series is also available in chip form.
resistance and ultra high-speed switching characteristics.
Two FET devices are built into the one package.
Because high-speed switching is possible, the IC can be efficiently set thereby saving energy.
The small SOP-8 package makes high density mounting possible.
