XC2173 Series
ICs for use with Crystal Oscillators (PLL built - in)
ETR1504_001a
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
