1 . GHz DIVIDE BY PRESCALER UPB5GV FEATURES TEST CIRCUIT HIGH FREUENCY OPERATION TO GHz FIXED DIVIDE RATIO: LOW CURRENT CONSUMPTION: 5 ma at 5 V SMALL PACKAGE: 8 PIN SSOP AVAILABLE IN TAPE AND REEL Power Supply pf 5 V ±.5 V pf 8 OPEN DESCRIPTION NEC's UPB5GV is a Silicon RFIC digital prescaler manufactured with the NESAT IV silicon bipolar process. It features frequency response to GHz, a divide-by-four ratio, and operates on a 5 volt supply while drawing only 5 ma. The device is housed in a small 8 pin SSOP package that contributes to system miniaturization. The low power consumption and wide frequency operation makes the device well suited for use in a PLL synthesizer for UHF/VHF TV and DBS tuner applications.

This pin must be decoupled with a bypass capacitor (e.g. pf). IN Signal input pin. This pin should be coupled to source with a capacitor (e.g. pf). IN Signal input bypass pin. This pin must be equipped with a bypass capacitor (e.g. pf) to ground. GND Ground pin. Ground pattern on the board should be formed as wide as possible to minimize ground impedance. 5 GND 6 NC No connection, this pin should be left open. 7 OUT Divided frequency output pin. This pin is designed as an emitter follower output, and should be coupled to the load with a capacitor (e.g. pf). 8 NC No connection, this pin should be left open.
