Dual Serial Input PLL Frequency Synthesizer
MB15F07SL
s DESCRIPTION
The Fujitsu MB15F07SL is a serial input Phase Locked Loop (PLL) frequency synthesizer with two 1100 MHz prescalers. The two 1100 MHz prescalers have a dual modulus division ratio of 128/129 or 64/65 enabling pulse swallowing operation. The supply voltage range is between 2.4 V and 3.6 V. The MB15F07SL uses the latest BiCMOS process. As a result, the supply current is typically 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. MB15F07SL is ideally suited for wireless mobile communications, such as GSM and PDC.
