Fujitsu MB15F86UL manual MB15F8xUL Series, Fractional-N / Integer dual PLL Frequency Synthesizers

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.
