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. ■Pin Configuration CE 1 ６ CLKin VSS ２ ５ VDD Q0 ３ ４ Output Frequency : 3MHz ~ 30MHz (Q0=fCLKin × N/M) Reference Oscillation (fCLKin) : 12KHz ~ 35MHz Divider Ratio (M) : Selectable from divisions of 1, 3 ~ 2047 Multiplier Ratio (N) : Selectable from multiplications of 6 ~ 2047 Output : 3-State Q1 output selectable from input reference oscillation, input reference oscillation/2, GND, comparative frequency.

Rq1 fQ1 fCLKin 6 1 5 4 XC25BS5 VDD 0.1μF 1 2 3 Rq0 R1 fQ0 C1 w Q1 Pin - GND fCLKin 6 5 4 XC25BS5 VDD 0.1μF 1 2 R1 C1 3 Rq0 fQ0 ■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 occurance 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 is 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 × C0.1µF 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. 100 XC25BS5 Series ■Reference Land Pattern q Q1 Pin - reference oscillation, reference oscillation/2, comparative frequency. 0.7 1.9 1.0 1 2.4 by-pass capacitor C=0.1μF matching resistor (mm) w Q1 Pin - GND 0.7 1.9 1.0 2.4 by-pass capacitor C=0.1μF matching resistor (mm) 101 XC25BS5 Series ■AC Characteristic Waveforms 1) Output Rise Time / Output Fall Time Output Waveform 0.8VDD 0.8VDD 1 DUTY Test Level 0.5VDD 0.2VDD TW TTLH 0.2VDD TTHL 2) Duty Ratio Output Waveform DUTY Test Level 0.5VDD TW T DUTY =(TW/T) 3) Output Start Time VIH CE Input Ton Output (Hi-Z) 102 ×100 (%)
