Description

The Fujitsu MB15F03SLPV2-G-EF is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1750 MHz and a 600 MHz prescalers. It has 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 MB15F03SLPV2-G-EF uses the latest BiCMOS process, resulting in a supply current of typically 3.5 mA at 2.7 V. It has a refined charge pump that supplies a well-balanced output current of 1.5 mA or 6 mA, which is selectable by serial data. The MB15F03SLPV2-G-EF is ideally suited for wireless mobile communications, such as GSM and PDC.
