The Fujitsu MB15F03SL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1750 MHz and a 600 MHz prescalers. The 1750 MHz prescaler, and 600 MHz prescaler have a dual modulus division ratio of 64/65 or 128/129 and 8/9 or 16/17 enabling pulse swallow operation.
The supply voltage range is between 2.4 V and 3.6 V.
The MB15F03SL uses the latest BiCMOS process. As a result, the supply current is typically 3.5 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.
MB15F03SL is ideally suited for wireless mobile communications, such as GSM and PDC.
