MB15F03SL

www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS04-21357-2E ASSP Dual Serial Input PLL Frequency Synthesizer MB15F03SL s DESCRIPTION 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. s FEATURES High frequency operation: RF synthesizer: 1750 MHz max IF synthesizer: 600 MHz max Low power supply voltage: VCC = 2.4 to 3.6 V Ultra Low power supply current: ICC = 3.5 mA typ. (VCC = 2.7 V, Ta = +25°C, in IF, RF locking state) ICC = 4.0 mA typ. (VCC = 3.0 V, Ta = +25°C, in IF, RF locking state) Direct power saving function: Power supply current in power saving mode Typ. 0.1 µA (VCC = 3V, Ta = +25°C), Max. 10 µA (VCC = 3V) Dual modulus prescaler: 1750 MHz prescaler (64/65 or 128/129)/600 MHz prescaler (8/9 or 16/17) Serial input 14-bit programmable reference divider: R = 3 to 16,383 Serial input programmable divider consisting of: - Binary 7-bit swallow count...
