MB15F74UV

www.DataSheet4U.com Aug. 2003 Edition 0.2 ASSP Dual Serial Input PLL Frequency Synthesizer(Small Package) MB15F74UV „ DESCRIPTION The Fujitsu MB15F74UV is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 4000MHz and a 2000MHz prescalers. A 64/65 or a 128/129 for the 4000MHz prescaler, and a 32/33 or a 64/65 for the 2000MHz prescaler can be selected for the prescaler that enables pulse swallow operation. The latest BiCMOS process is used, as a result a supply current is typically 9.0mA typ. at 3.0V. The supply voltage range is from 2.7V to 3.6V. A refined charge pump supplies well-balanced output current with 1.5mA and 6mA selectable by serial data. The data format and the function as fast locking are same as the previous one MB15F74UL. The new package(BCC18) decreases a mount area of MB15F74UV about 50% comparing with the former BCC20(for dual PLL, MB15F74UL). MB15F74UV is ideally suited for wireless mobile communications, such as W-CDMA. „ FEATURES Very small package: BCC18 (2.4*2.7*0.45mm) High frequency operation: RF synthesizer : 4000MHz max IF synthesizer : 2000MHz max Low power supply voltage: VCC = 2.7 to 3.6 V Ultra Low power supply current : ICC = 9.0 mA typ. (VCC = 3.0V, Ta=25°C, SW=0 in RF, IF locking state) Direct power saving function : Power supply current in power saving mode Typ. 0.1 µA(Vcc=3.0V, Ta=25°C), Max. 10 µA(Vcc=3.0V) Dual modulus prescaler : 4000MHz prescaler(64/65 or 128/129) / 2000MHz prescaler(32/33 or 64/65) ...
