XC25BS5 Series
ETR1502_003a
PLL Clock Generator ICs with Built-In Divider/Multiplier Circuits
(For Low Frequency Range)
■GENERAL DESCRIPTION
The XC25BS5 series are high frequency, low power consumption PLL clock generator ICs with divider circuit & multiplier
PLL circuit.
Laser trimming gives the option of being able to select from divider ratios (M) of 1,3 to 2047 and multiplier ratios (N) of 6 to
2047.
Output frequency (Q0) is equal to reference oscillation (fCLKin) multiplied by N/M, within a range of 3MHz to 30MHz. Q1
output is selectable from input reference frequency (f0), input reference frequency/2 (f0/2), ground (GND), and comparative
frequency (f0/M). Further, comparative frequencies, within a range of 12KHz to 500KHz, can be obtained by dividing the
reference oscillation. By halting operation via the CE pin, consumption current can be controlled and output will be one of
high-impedance.

■TYPICAL APPLICATION CIRCUITS
① Q1 Pin - reference oscillation, reference oscillation/2, comparative frequency
② Q1 Pin - GND
■NOTE
(1) Please insert a by-pass capacitor of 0.1μF.
(2) Rq0 and Rq1 are matching resistors. Their use is recommended in order to counter unwanted radiations.
(3) Please place a by-pass capacitor and matching resistors as close to the IC as possible. It may be that the
output cannot be locked if the by-pass capacitor is not close enough to the IC. Further, there is a possibility of
unwanted radiation occurrence between the resistor and the IC pin if the matching resistor is not close enough to
the IC.
(4) When selecting GND for the Q1 pin, although the output of Q1 pin is GND level, it is also recommended that the
Q1 pin be connected to GND pattern on the PCB.
(5) When the CE pin is not controlled by external signals, it is recommended that a time constant circuit of R1=1kΩ
×C1 = 0.1μF be added for stability.
(6) 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, so all necessary precautions should be taken to avoid this.
(7) It 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.
(8) 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.
