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)

20-pin, Plastic TSSOP

20-pad, Plastic BCC

provides fast tuning along with low spurious noise and phase

noise characteristics. The MB15F8xUL series is ideally suited for

FPT-20P-M06

LCC-20P-M05

digital mobile communications, including GSM, DCS1800,

 

 

 

PCS1900, IS-136, IS-95 and ISM applications.
