XC25BS3 series

      The XC25BS3 series are designed for Crystal oscillation modules;Microcontroller;PDAs;Portable audio systems;Various system clocks.The XC25BS3 series has features including Output Frequency : 9MHz ~ 80MHz (Q0=fCLKin*N/M);Reference Oscillation (fCLKin): 14kHz ~ 35MHz;Divider Ratio (M) : Selectable from divisions of 1 ~ 2047;Multiplier Ratio (N) : Selectable from multiplications of 20 ~ 2047.
      The XC25BS3 series are high frequency, low power consumption PLL clock generator ICs with built-in crystal oscillator circuit, divider circuit & multiplier PLL circuit. Laser trimming gives the option of being able to select from divider ratios (M) of 1 to 2047 and multiplier ratio (N) of 20 to 2047. Output frequency (Q0) is equal to reference oscillation (fCLKin) multiplied by N/M, within a range of 9MHz to 80MHz.Q1 output is selectable from input reference frequency (f0),Ground (GND), PLL output frequency/2 (Q0/2), and comparative frequency/2 (f0/M/2). Reference oscillation can input 14kHz to 35MHz of reference clock. Further, comparative frequency, within a range of 14kHz to 500kHz, can be obtained by dividing the reference oscillation. By halting oscillation via the CE pin, consumption current can be controlled. Output will be one of high impedance.
      XC25BS3 series is recommended that a low noise power supply, such as a series regulator, be used for the supply voltage. Using a power supply such as a switching regulator might lead to a larger jitter, which in turn may lead to an inability to lock due to the ripple of the switching regulator. As for this IC, synchronization of input and output signal's edge is not guaranteed though the input frequency operates to the output frequency multiply.The XC25BS3 series specifications contained herein are subject to change without notice to improve performance characteristics.
