Series

■GENERAL

DESCRIPTION

ETR1506-007a

Ultra Small PLL Clock Generator ICs with Built-In Divider/Multiplier Circuits

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 (f

CLKin

) 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 ±5％ of 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.
