XC25BS8 Series

Ultra Small PLL Clock Generator ICs with Built-In Divider/Multiplier Circuits
GENERAL DESCRIPTION
The XC25BS8 series is an ultra small PLL clock generator IC which can generate a high multiplier output up to 4095 from an input frequency as
low as 8kHz. The series includes a divider circuit, phase/frequency comparator, charge pump, and VCO so it is possible to configure a fully
operational circuit with a few external components like one low-pass filter capacitor. The Input divider ratio (M) can be selected from a range of 1
to 2047, the output divider ratio (N) can be selected from a range of 1 to 4095 and they are set internally by using laser timing technologies.
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 operation and current drain is suppressed when a low level signal is input to the
CE pin which greatly reduces current consumption and produces a high impedance output.
The setting of the input divider ratio (M), output divider ratio (N), and charge pump current (Ip) are factory fixed semi-custom. Please advise your
Torex sales representative of your particular input/output frequency and supply voltage specifications so that we can see if we will be able to
support your requirements. The series is available in small SOT-26W and USP-6C.

*1: The series are semi-custom products. Specifications for each
product are limited within the above range. The input frequency
range is set within ±5of customer’s designated typical frequency.
Please note that setting of your some requirements may not be
possible due to the specification limits of this series.
*2: When the IC is in stand-by mode, the output becomes high impedance
and the IC stops operation.

NOTE:
*1: The values are measured when a capacitor CIN=0.1μF is connected between VDD and VSS pins, a capacitor C1=0.1μF is connected
between LFP and VSS pins
*2: It is a time to get stable output signal from Q0 pin after the CE pin is turned on while applying supply voltage to the VDD pin and applying the
input signal to the CLKin pin.
*3: Values indicated are design values which are not guaranteed 100%.
