■General Description
The XC2173 series are high frequency, low power consumption CMOS
ICs with built-in crystal oscillator, divider and clock 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.
