ICs for use with Crystal Oscillators (PLL built‐in)

Series

1039

14

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.
