DESCRIPTION
The Fujitsu MB15F03 is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2.0GHz and a 500MHz
prescalers. A 64/65 or a 128/129 for the 2.0GHz prescaler, and a 16/17 or a 32/33 for 500MHz 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 9.0mA 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, MB15F03 is ideally suitable for digital mobile communications, such as PHS(Personal Handy Phone
System), PCN (Personal Communication Network) and PCS(Personal Communication Service).
