GENERAL DESCRIPTION
The XC25BS3 series are high frequency, low power consumption PLL clock generator ICs with built-in crystal oscillator circuit, divider circuit & multiplier PLL circuit. Laser trimming gives the option of being able to select from divider ratios (M) of 1 to 2047 and multiplier ratio (N) of 20 to 2047. Output frequency (Q0) is equal to reference oscillation (fCLKin) multiplied by N/M, within a range of 9MHz to 80MHz. Q1 output is selectable from input reference frequency (f0), Ground (GND), PLL output frequency/2 (Q0/2), and comparative frequency/2 (f0/M/2). Reference oscillation can

TYPICAL APPLICATION CIRCUITS
Circuit Example
Q1 Pin - reference oscillation, PLL output frequency/2, comparative frequency/2
Q1 Pin - GND
NOTES ON USE
(1) Please insert a by-pass capacitor of 0.1F. (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. The output may not 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 resistors are not close enough to the IC. (4) When selecting GND for the Q1 pin, although the IC will be connected to GND internally, it is also recommended that the PCB be connected to GND. (5) When the CE pin is not controlled by external signals, it is recommended that a time constant circuit of R1=1kx C1=0.1F be added for stability. (6) With this IC, output is achieved by dividing and multiplying the reference oscillation by means of the PLL circuit. may increase, 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. In cases where this output is further used as a reference oscillation of another PLL circuit, the final output signal's jitter
