MB15U36
Dual PLL Frequency Synthesizer
with On-Chip Prescaler
Description
The Fujitsu MB15U36 dual PLL is a serial input frequency
synthesizer with 2.0 GHz and 1.2 GHz prescalers.The
prescalers both have a selectable dual modulus division ratio
of 64/65 or 128/129 enabling pulse swallow operation. The
MB15U36 utilizes a refined charge pump design (Fujitsu’s
Super Charger)that provides fast tuning along with low
spurious noise and phase noise characteristics. The MB15U36
is ideally suited for digital mobile communications, including
GSM, DCS1800, PCS1900, IS-136, IS-95 and ISM-band
applications.
