UPB587G

1.0 GHz DIVIDE- BY- 2/4/8 PRESCALER UPB587B* UPB587G *B VERSION FOR HI-REL APPLICATIONS ONLY 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-byfour or divide-by-eight mode. They feature frequency response 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 include: 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.
