■DESCRIPTION

The Fujitsu MB15F73UL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2250 MHz and

a 600 MHz prescalers. A 64/65 or a 128/129 for the 2250 MHz prescaler, and a 8/9 or a 16/17 for the 600 MHz prescaler can be selected for the prescaler that enables pulse swallow operation.

■FEATURES

? High frequency operation : RF synthesizer : 2250 MHz Max.

: IF synthesizer : 600 MHz Max.

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

? Ultra low power supply current : ICC =3.2 mA Typ.

(VCC =Vp =2.7 V, Ta = +25 °C, SWIF =SWRF =0 in IF/RF locking state)

? Direct power saving function : Power supply current in power saving mode
