DESCRIPTION
The UPB1511TB is a silicon monolithic integrated circuit designed as a divide by 2,4 prescaler IC for portable radio systems. This IC is manufactured using NEC's 30 GHz fMAX UHS0 (Ultra High Speed Process) silicon bipolar process. Consequently, this IC is lower circuit current and smaller package than conventional UPB1509GV. The low power makes this device ideally suited for cellular and cordless telephone applications. NEC's stringent quality assurance and test procedures ensure the highest reliability and performance.

APPLICATIONS
* Portable radio systems * Cellular/cordless telephone 2nd local prescaler

PIN EXPLANATIONS
PIN NO. 1 SYMBOL OUT APPLIED VOLTAGE (V) - FUNCTIONS AND EXPLANATION Divided Frequency Output Pin. This pin is designed as an emitter follower output and can deliver 0.2 VP-P minimum into a 200 load. This pin should be coupled to the load device with a capacitor (example: 1000 pF) for DC cut. Ground Pin. Ground pattern on the board should be as wide as possible to minimize ground impedance. Divide Ratio Control Pin. Divide ratio can be determined by the following applied level to these pins.
