■DESCRIPITON

The Fujitsu MB15F03L is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1800MHz and a 250MHz prescalers. A 64/65 or a 128/129 for the 1800MHz prescaler, and a 16/17 or a 32/33 for 250MHz 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 5.0mA 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, MB15F03L is ideally suitable for digital mobile communications, such as PHS(Personal Handy Phone System), PCN (Personal Communication Network) and PCS(Personal Communication Service).
