www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS04-21360-4E ASSP Single Serial Input PLL Frequency Synthesizer On-chip 2.0 GHz Prescaler MB15E05SL s DESCRIPTION The Fujitsu MB15E05SL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2.0 GHz prescaler. The 2.0 GHz prescaler has a dual modulus division ratio of 64/65 or 128/129 enabling pulse swallowing operation. The supply voltage range is between 2.4 V and 3.6 V. The MB15E05SL uses the latest BiCMOS process, as a result the supply current is typically 3.0 mA at 2.7 V. A refined charge pump supplies well-balanced output currents of 1.5 mA and 6 mA. The charge pump current is selectable by serial data. MB15E05SL is ideally suited for wireless mobile communications, such as GSM (Global System for Mobile Communications) and PCS. s FEATURES High frequency operation: 2.0 GHz max Low power supply voltage: VCC = 2.4 to 3.6 V Ultra Low power supply current: ICC = 3.0 mA typ. (VCC = Vp = 2.7 V, Ta = +25°C, in locking state) ICC = 3.5 mA typ. (VCC = Vp = 3.0 V, Ta = +25°C, in locking state) Direct power saving function: Power supply current in power saving mode Typ. 0.1 µA (VCC = Vp = 3.0 V, Ta = +25°C), Max. 10 µA (VCC = Vp = 3.0 V) Dual modulus prescaler: 64/65 or 128/129 Serial input 14-bit programmable reference divider: R = 3 to 16,383 Serial input programmable divider consisting of: - Binary 7-bit swallow counter: 0 to 127 - Binary 11-bit programmable counter: 3 to 2,047 Software s...
