MB15F76UL

www.DataSheet4U.com Jun. 2001 Edition 0.2 ASSP Dual Serial Input PLL Frequency Synthesizer MB15F76UL n DESCRIPTION The Fujitsu MB15F76UL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 6000MHz and a 1500MHz prescalers. Both IF and RF PLL section have a 1/4 divider. And a 16/17 or a 32/33 for the 6000MHz prescaler, and a 4/5 or a 8/9 for the 1500MHz 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. Fast locking is acheived for adopting the new circuit. The new package(BCC20) decreases a mount area of MB15F76UL more than 30% comparing with the former BCC16(for dual PLL). MB15F76UL is ideally suited for wireless communications, such as W-LAN. n FEATURES High frequency operation: RF synthesizer : 6000MHz max IF synthesizer : : 1500MHz max Low power supply voltage: V C C = 2.7 to 3.6 V Ultra Low power supply current : I C C = 9.0 mA typ. (VCC = V p =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=Vp=3.0V, Ta=25 °C), Max. 10 µ A(Vcc=Vp=3.0V) Dual modulus prescaler : 6000MHz prescaler(16/17 or 32/33, and 1/4divider) 1500MHz prescaler(4/5 or 8/9, and 1/4divider) Serial input 14-b...
