s DESCRIPTION

The Fujitsu MB15F08SL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2500 MHz and a

1100 MHz prescalers. The 2500 MHz prescaler, and 1100 MHz prescaler have a dual modulus division ratio of 32/

33 or 64/65 and 16/17 or 32/33 enabling pulse swallow operation.

The supply voltage range is between 2.4 V and 3.6 V.

The MB15F08SL uses the latest BiCMOS process. As a result, the supply current is typically 7.0 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.

MB15F08SL is ideally suited for wireless mobile communications.

s FEATURES

• High frequency operation: RX synthesizer: 2500 MHz max

TX synthesizer: 1100 MHz max

• Low power supply voltage: VCC = 2.4 to 3.6 V

• Ultra Low power supply current: ICC = 7.0 mA typ. (VCC = 2.7 V, Ta = +25°C, in TX, RX locking state)

ICC = 7.5 mA typ. (VCC = 3.0 V, Ta = +25°C, in TX, RX 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: 2500 MHz prescaler (32/33 or 64/65)/1100 MHz prescaler (16/17 or 32/33)

• 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

• Operating temperature: Ta = –40 to +85°C
