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.

Series
■NOTE ON USE
(1) Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be
exceeded.
(2) The series is an analog IC. Please use a 0.01μF to 0.1μF of a by-pass capacitor.
(3) The constant of the LPF element of this IC is preset. Always use the capacitance value (=0.1μF) specified by us for
the external ceramic capacitor (C1) for LPF. Operating this IC with a capacitor of the wrong capacitance will cause
erroneous operation.
(4) Rq0 shown in the Typical Application Circuit is a matching resistor. The use is recommended in order to counter
unwanted radiations.
(5) Please place the by-pass capacitor and the matching resistor as close to the IC as possible. The IC may not operate
normally if the by-pass capacitor is not close enough to the IC. Further, the unwanted radiation may occur between
the resistor and the IC pin if the matching resistor is not close enough to the IC.
(6)When the CE pin is not controlled by external signals, it is recommended that a time constant circuit of R1=1kΩ ×C2
= 0.1μF be added for stability.
(7) With this IC, output is achieved by dividing and multiplying the reference oscillation by means of the PLL circuit. In
cases where this output is further used as a reference oscillation of another PLL circuit, it may be that the final output
signal's jitter increases; therefore, all necessary precautions should be taken to avoid this.
(8) It is recommended that a low noise power supply, such as a series regulator, be used as the series’ supply voltage.
Using a power supply such as a switching regulator may enlarge the jitter, which in turn may lead to abnormal
operation. Please confirm its operation with the actual device.
(9) For operating the IC normally, please take procedures below when applying voltage to the series’ input pin:
1) Apply power source while the CE pin is "L" level with no clock input (high-Impedance or “L”),
2) Input the clock,
3) At least 100μs after applying clock input, change the CE pin into “H” level and then to enable.
The IC has to be started by inputting the clock once the power rises completely. The CE pin, then, should be enabling.
If the CE pin becomes enable and the clock is inputted before the power rises completely, an internal reset circuit
does not operate normally which may cause to generate extraneous frequency.
●eg.)Matching Resistance （Rq0） and Device for Time constant circuit (R1,C2）are connected,

■NOTE ON USE (Continued)
●Instructions on Pattern Layout
1. In order to stabilize VDD voltage level, we recommend that a by-pass capacitor (CIN) be connected as close as possible to
the VDD and VSS pins.
2. Please mount the low pass filter capacitor C1(=0.1μF) as close to the IC as possible.
3. Make the pattern as close to the IC as possible and use thick, short connecting traces to reduce the circuit impedance.
4. Make sure that the VSS (GND) traces are as thick as possible, as variations in ground potential caused by noise may
result in instability of this product.
