The Fujitsu MB15F08SL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2500 MHz and a 1100 MHz prescalers. The 2500 MHz prescaler, and 1100 MHz prescaler have a dual modulus division ratio of 32/33 or 64/65 and 16/17 or 32/33 enabling pulse swallow operation.
The supply voltage range is between 2.4 V and 3.6 V.
The MB15F08SL uses the latest BiCMOS process. As a result, the supply current is typically 7.0 mA at 2.7 V. A refined charge pump supplies a well-balanced output current of 1.5 mA or 6 mA. The charge pump current is selectable by serial data.
MB15F08SL is ideally suited for wireless mobile communications.
