DESCRIPTION
The Fujitsu MB15F02L is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1.2 GHz and a 250
MHz prescalers. A 64/65 or a 128/129 for the 1.2 GHz prescaler, and a 16/17 or a 32/33 for 250 MHz prescaler can
be selected that enables pulse swallow operation.
The latest BiCMOS process technology is used, resuItantly a supply current is limited as low as 4.0 mA typ. at a
supply voltage of 3.0 V.
Furthermore, a super charger circuit is included to provide a fast tuning as well as low noise performance. As a result
of this, MB15F02L is ideally suitable for digital mobile communications, such as GSM (Global System for Mobile
Communications).
