DESCRIPTION

The Fujitsu MB15F05L is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1800MHz and a 233.15MHz prescalers. A 64/65 or a 128/129 for the 1800MHz prescaler, and a 16/17 for the 233.15MHz prescaler can be selected that enables pulse swallow operation.

FEATURES

• High frequency operationRF synthesizer: 1800MHz max. / IF synthesizer: 233.15MHz fixed

• Low power supply voltage: VCC = 2.7 to 3.6V

• Very Low power supply current : ICC = 5.0 mA typ. (Vcc = 3V)

• Power saving function : Supply current at power saving mode Typ.0.1µA (Vcc=3V), Max.10µA (IPS1=IPS2)

• Dual modulus prescaler : 1800MHz prescaler(64/65,128/129)

• Serial input 14–bit programmable reference divider: R = 5 to 16,383

• Serial input 18–bit programmable divider consisting of:

- Binary 7–bit swallow counter: 0 to 127

- Binary 11–bit programmable counter: 5 to 2,047

• On–chip high performance charge pump circuit and phase comparator, achieving high–speed lock–up and low phase noise

• On–chip phase control for phase comparator

• Wide operating temperature: Ta = -40 to 85˚C
