DESCRIPTION
The Fujitsu MB15F04 is a serial input Phase Locked Loop (PLL) frequency synthesizer with two 2.0GHz prescalers. A 64/65 or a 128/129 for both 2.0GHz prescalers can be selected that enables pulse swallow operation. The latest BiCMOS process technology is used, resuItantly a supply current is limited as low as 11.0mA typ. at a supply voltage of 3.0V. Furthermore, a super charger circuit is included to provide a fast tuning as well as low noise performance. As a result of this, MB15F04 is ideally suitable for digital mobile communications. s
FEATURES
• High frequency operation • • • • • RX synthesizer : 2.0 GHz max. TX synthesizer : 2.0 GHz max.
