MB15F05L

www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS04-21351-1E ASSP Dual Serial Input PLL Frequency Synthesizer MB15F05L s DESCRIPTION The Fujitsu MB15F05L is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1800MHz and a 233.15MHz prescalers. A 64/65 or a 128/129 for the 1800MHz prescaler, and a 16/17 for the 233.15MHz prescaler can be selected that enables pulse swallow operation. The latest BiCMOS process technology is used, resuItantly a supply current is limited as low as 5.0mA typ. at a supply voltage of 3.0V. Furthermore, a super charger circuit is included to provide a fast tuning as well as low noise performance. As a result of this, MB15F05L is ideally suitable for digital mobile communications, such as PHS(Personal Handy Phone System). s FEATURES High frequency operationRF synthesizer: 1800MHz max. / IF synthesizer: 233.15MHz fixed Low power supply voltage: VCC = 2.7 to 3.6V Very Low power supply current : ICC = 5.0 mA typ. (Vcc = 3V) Power saving function : Supply current at power saving mode Typ.0.1µA (Vcc=3V), Max.10µA (IPS1=IPS2) Dual modulus prescaler : 1800MHz prescaler(64/65,128/129) Serial input 14–bit programmable reference divider: R = 5 to 16,383 Serial input 18–bit programmable divider consisting of: - Binary 7–bit swallow counter: 0 to 127 - Binary 11–bit programmable counter: 5 to 2,047 On–chip high performance charge pump circuit and phase comparator, achieving high–speed lock–up and low phase noise On–chi...
