XC2163 Series
ICs for use with 3rd Overtone Crystal Oscillators
ETR1403_001a
ç
ç _{˙GENERAL DESCRIPTION}
ç _{The XC2163 series are high frequency, low current consumption CMOS ICs with built-in crystal oscillator and divider circuits.}
ç _{Output is selectable from any one of the following values for f0: f0/1, f0/2, f0/4, f0/8.}
ç _{With oscillation capacitors and a feedback resistors built-in, it is possible to configure a stable 3rd overtone oscillator using}
ç
ç ^{only an external crystal oscillator.}
ç ^{Also available is an external oscillation capacitor/external oscillation feedback resistor type, which makes oscillation}
ç ^{frequency control possible.}
