■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.

■APPLICATIONS

●Crystal oscillation modules

●Computer, DSP clocks

●Communication equipment

●Various system clocks
