General Description
The XC25BS8 series are ultra small package PLL clock generator ICs which multiply low frequency inputs from 8kHz up to 4095 times.
A divider circuit, phase/frequency comparator, charge pump, and VCO are built-in. This series are used by adding an external capacitor for low-pass filter.
Input divider ratios (M) are from 1 to 2047 and output divider ratios (N) are from 1 to 4095, and can be selected by trimming. Output frequency (fQ0) is equal to input
clock frequency (FCLKin) multiplied by N/M. Output frequency range is 1MHz to 100MHz. Reference clock from 8kHz to 36MHz can be input as the input clock.
The IC stops operating and current drain is suppressed when a low level signal is input to the CE pin. At this time, the output becomes high impedance.
Since the input divider ratio (M), output divider ratio (N), and charge pump current (Ip) settings of this series are factory fixed semi-custom,
please ask your Torex sales contact for your requested specifications such as input/output frequency and supply voltage.
However, please note that setting of your requested specifications may be impossible due to the specification limits of this series.
