s DESCRIPTION
The Fujitsu MB15F03SL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1750 MHz and a
600 MHz prescalers. The 1750 MHz prescaler, and 600 MHz prescaler have a dual modulus division ratio of 64/65
or 128/129 and 8/9 or 16/17 enabling pulse swallow operation.
The supply voltage range is between 2.4 V and 3.6 V.
The MB15F03SL 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 a well-balanced output current of 1.5 mA or 6 mA. The charge pump current is selectable
by serial data.
MB15F03SL is ideally suited for wireless mobile communications, such as GSM and PDC.
s FEATURES
• High frequency operation: RF synthesizer: 1750 MHz max
IF synthesizer: 600 MHz max
• Low power supply voltage: VCC = 2.4 to 3.6 V
• Ultra Low power supply current: ICC = 3.5 mA typ. (VCC = 2.7 V, Ta = +25°C, in IF, RF locking state)
ICC = 4.0 mA typ. (VCC = 3.0 V, Ta = +25°C, in IF, RF locking state)
• Direct power saving function: Power supply current in power saving mode
Typ. 0.1 µA (VCC = 3V, Ta = +25°C), Max. 10 µA (VCC = 3V)
• Dual modulus prescaler: 1750 MHz prescaler (64/65 or 128/129)/600 MHz prescaler (8/9 or 16/17)
• Serial input 14-bit programmable reference divider: R = 3 to 16,383
• Serial input programmable divider consisting of:
- Binary 7-bit swallow counter: 0 to 127
- Binary 11-bit programmable counter: 3 to 2,047
• Software selectable charge pump current
• On–chip phase control for phase comparator
