FUJITSU SEMICONDUCTOR DS04213596E DATA SHEET ASSP Single Serial Input PLL Frequency Synthesizer On-chip 1.2 GHz Prescaler MB15E03SL DESCRIPTION The Fujitsu Semiconductor MB15E03SL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1.2 GHz prescaler. The 1.2 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 MB15E03SL uses the latest BiCMOS process, as a result, the supply current is typically 2.0 mA at 2.7 V. A refined charge pump supplies a well balanced output currents of 1.5 mA or 6 mA. The charge pump current is selectable by serial data. FEATURES High frequency operation: 1.2 GHz max Low power supply voltage: VCC = 2.4 V to 3.6 V Ultra Low power supply current:ICC = 2.0 mA typ. (VCC = Vp = 2.7 V, Ta = +25C, in locking state) ICC = 2.5 mA typ. (VCC = Vp = 3 V, Ta = +25C, in locking state) Direct power saving function: Power supply current in power saving mode Typ. 0.1 A (VCC = Vp = 3 V, Ta = +25C), Max. 10 A (VCC = Vp = 3 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 Selectable charge pump current On-chip phase control for phase comparator Operating temperature: Ta = 40 to +85C Copyright2000-2012 FUJITSU SEMICONDUCTOR LIMITED All rights reserved 2012.5
