■DESCRIPTION

The Fujitsu MB15F04 is a serial input Phase Locked Loop (PLL) frequency synthesizer with two 2.0GHz prescalers. A 64/65 or a 128/129 for both 2.0GHz prescalers can be selected that enables pulse swallow operation. The latest BiCMOS process technology is used, resuItantly a supply current is limited as low as 11.0mA typ. at a supply voltage of 3.0V.

■FEATURES

• High frequency operation RX synthesizer : 2.0 GHz max. TX synthesizer : 2.0 GHz max.

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

• Very Low power supply current : ICC = 11.0 mA typ. (Vcc = 3V)

• Power saving function : IPSTX= IPSTX= 10µA max.

• 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

• Wide operating temperature: Ta = −40 to 85°C
