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.

FEATURES
• High frequency operation: RF synthesizer : 6000MHz max
                                             IF synthesizer: : 1500MHz max
• Low power supply voltage: V CC = 2.7 to 3.6 V
• Ultra Low power supply current : ICC = 9.0 mA typ. (VCC = Vp=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 mA(Vcc=Vp=3.0V, Ta=25°C), Max. 10 mA(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-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
