MB15F8xUL Series
Fractional-N / Integer dual
PLL Frequency Synthesizers
DESCRIPTION
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.
FEATURES

Page 6: Evaluation Systems
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.
