DESCRIPTION
The Fujitsu MB15F73UV is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2250 MHz and a 600 MHz prescalers. A 64/65 or a 128/129 for the 2250 MHz prescaler, and a 8/9 or a 16/17 for the 600 MHz prescaler can be selected for the prescaler that enables pulse swallow operation.

FEATURES
• High frequency operation : RF synthesizer : 2250 MHz Max
                                            : IF synthesizer : 600 MHz Max
• Low power supply voltage : VCC = 2.4 V to 3.6 V
• Ultra low power supply current : ICC = 3.2 mA Typ
    (VCC = 2.7 V, Ta = +25 °C, SWIF = SWRF = 0 in IF/RF locking state)
• Direct power saving function : Power supply current in power saving mode
    Typ 0.1 µA (VCC = 2.7 V, Ta = +25 °C)
    Max 10 µA (VCC = 2.7 V)
• Software selectable charge pump current : 1.5 mA/6.0 mA Typ
• Dual modulus prescaler : 2250 MHz prescaler (64/65 or128/129) /600 MHz prescaler (8/9 or 16/17)
