1.0 GHz DIVIDE- BY- 2/4/8 PRESCALER
FEATURES
HIGH FREQUENCY OPERATION TO
1 GHz
LOW SUPPLY VOLTAGE:
2.2 V to 3.5 V
LOW SUPPLY CURRENT:
5.5 mA
AVAILABLE IN TAPE AND REEL
(G08 PACKAGE)
DESCRIPTION
The UPB587 series of devices are silicon bipolar digital
prescalers which can be operated in divide-by-two, divide-by-
four or divide-by-eight mode. They feature frequency re-
sponse to 1 GHz, and operate from a single 3 volt supply
drawing only 5.5 milliamps. The series is available in two
package styles: 8 lead ceramic flat pack (UPB587B), and an
8 pin plastic mini-flat package (UPB587G). Applications in-
clude: synthesizer for DBS receiver and telecommunication
applications. The low DC voltage required and power-saving
current draw make them ideal for hand-held, battery-powered
applications.
