20、BS3VDD0.1F123R1Rq0f00C1Directions for useNote:Please ert a by-pass capacitor of 0.1mF.Rq0 and Rq1 are matching resistors. Their use is recommended in order to counter unwanted radiations.Please place a by-pass capacitor and matching resistors as close to the IC as possible. It may be that the output

21、 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.When selecting GND for the Q1 pin, although the IC will be connected to

22、 GND internally, it is also recommended that the PCB be connected to GND.When the CE pin is not controlled by external signals, it is recommended that a time constant circuit of R1=1kW C1mF be added forstability.With this IC, output is achieved by dividing and multiplying the reference oscillation b

23、y 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 signals jitter increases, so all necessary precautions should be taken to avoid this.It is recommended that a low noise power supply, such as a series r
