MB15F8xUL Series  
Fractional-N / Integer dual  
PLL Frequency Synthesizers  
DESCRIPTION  
Packages  
The Fujitsu MB15F8xUL series dual PLLs are serial input  
Frequency synthesizers. The Fractional-N PLL operates up to 2.6  
GHz and the integer PLL operates up to 1200 MHz. They have  
built-in dual-modulus prescalers enabling pulse swallow operation  
and fixed or selectable fractional modulo. The latest advanced  
BiCMOS technology is used resulting in a super low supply  
current. A refined charge pump design (Fujitsu’s Super Charger)  
provides fast tuning along with low spurious noise and phase  
noise characteristics. The MB15F8xUL series is ideally suited for  
digital mobile communications, including GSM, DCS1800,  
PCS1900, IS-136, IS-95 and ISM applications.

Evaluation Systems  
Designing a complex subsystem, such as a PLL, is no easy task. Therefore, Fujitsu has made available an  
evaluation system to aid in the development of reliable frequency synthesizers. Each evaluation system  
consists of two PCBs, controlling software, and instructions.  
The RF PCB is laid out to allow the target MB158xUL to be optimized for the chosen application. The RF  
board is only semi-populated, which allows the user to configure it to fit the application.
