ç _{˙GENERAL DESCRIPTION}
ç _{The XC2173 series are high frequency, low power consumption CMOS ICs with built-in crystal oscillator, divider and clock}
ç _{multiplier PLL circuits. Output is selectable from any one of the following values for f0: f0 x 5, f0 x 6, f0 x 7, f0 x 8, f0/2, f0/4,}
f0/8. With an oscillation capacitor & oscillation feedback resistor built-in, a stable oscillator circuit can be put together using
only an external crystal oscillator.
By connecting an external standard clock, the above mentioned output frequencies can be achieved.
