www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS04-21356-3E ASSP Dual Serial Input PLL Frequency Synthesizer MB15F02SL s DESCRIPTION The Fujitsu MB15F02SL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1200 MHz and a 500 MHz prescalers. The 1200 MHz and 500 MHz prescalers have a dual modulus division ratio of 128/129 or 64/65, and a 8/9 or a 16/17 enabling pulse swallowing operation. The supply voltage range is between 2.4 V and 3.6 V. The MB15F02SL uses the latest BiCMOS process. As a result, the supply current is typically 3 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. MB15F02SL is ideally suited for wireless mobile communications, such as GSM and PDC. s FEATURES • High frequency operation: RF synthesizer: 1200 MHz max IF synthesizer: 500 MHz max • Low power supply voltage: VCC = 2.4 to 3.6 V • Ultra Low power supply current: ICC = 3.0 mA typ.
