ASSP Dual Serial Input PLL Frequency Synthesizer(Small Package) MB15F76UV DESCRIPTION The Fujitsu MB15F76UV 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 BiCMOS process is used, as a result, a supply current is typically 8.5mA typ. at 3.0V. The supply voltage range is from 2.5V 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(BCC18) decreases a mount area of MB15F76UV about 50% comparing with the former BCC20(for dual PLL). MB15F76UV is ideally suited for wireless communications, such as W-LAN. FEATURES • Very small package: BCC18 (2.4*2.7*0.45mm) • High frequency operation: RF synthesizer : 6000MHz max IF synthesizer : 1500MHz max • Low power supply voltage: VCC = 2.5 to 3.6 V • Ultra Low power supply current : ICC = 8.5 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 : 6000MHz prescaler(16/17 or 32/33, and 1/4divider) • 1500MHz prescaler(4/5 or 8/9, and 1/4divider) • Serial input 14-bit programmable reference divider: R = 3 to 16,383 • Serial input programmable divider consisting of: - Binary 5-bit swallow counter: 0 to 31 - Binary 13-bit programmable counter: 3 to 8191 • On-chip phase comparator for fast lock and low noise • On-chip phase control for phase comparator • Operating temperature: Ta = –40 to 85 °C • Sireal data format compatible with MB15F76UL 18-pad, Plastic BCC (LCC-18P-M05) |
