DESCRIPTION

CL
The UPB1502GR prescaler operates from 0.5 to 1.7 GHz at
division ratios of 64, 65, 128 or 129. The 3 volt, 7 mA DC power
requirements of this device make it highly desirable for handheld, battery-operated systems. The low cost 8-pin plastic
package is suitable for surface mount applications.
PARAMETER
UNITS
Notes:
1. All Capacitors 1000 pF except load capacitor on output should
be 8 pF. Capacitors on SW and PSC are not required if these
pins are grounded.
2. Connect VENABLE pin to +3 volts for normal operation. Connect to
GND to disable device.
3. To minimize self-oscillation, circuit board traces to the input and
output pins should be isolated from each other as much as
possible.
