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. |
