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.
The XC2173 series are high‑frequency, low‑power CMOS crystal oscillator ICs that integrate a crystal, divider and clock‑multiplier PLL. They support external crystals and provide selectable output frequencies via built‑in multipliers and dividers.
The devices are offered in an 8‑pin SOT‑26 mini‑mold package, feature a standby control (INH) pin with an internal pull‑up resistor, and operate from 3.3 V or 5.0 V supplies. Detailed electrical characteristics, absolute maximum ratings and switching parameters are listed for each multiplier setting. This manual is written in Chinese.
