■ DESCRIPTION
The Fujitsu MB15E07SL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2.5 GHz prescaler. The 2.5 GHz prescaler has a dual modulus division ratio of 32/33 or 64/65 enabling pulse swallowing operation.
The supply voltage range is between 2.4 V and 3.6 V. The MB15E07SL uses the latest BiCMOS process, as a result the supply current is typically 3.5 mA at 2.7 V. A refined charge pump supplies well-balanced output currents of 1.5 mA and 6 mA. The charge pump current is selectable by serial data.

■ FEATURES
• High frequency operation: 2.5 GHz max
• Low power supply voltage: VCC = 2.4 to 3.6 V
• Ultra Low power supply current:ICC = 3.5 mA typ. (VCC = Vp = 2.7 V, Ta = +25°C, in locking state) ICC = 4.0 mA typ. (VCC = Vp = 3.0 V, Ta = +25°C, in locking state)
• Direct power saving function: Power supply current in power saving mode Typ. 0.1 µA (VCC = Vp = 3.0 V, Ta = +25°C), Max. 10 µA (VCC = Vp = 3.0 V)
• Dual modulus prescaler: 32/33 or 64/65
