Analog Devices ADF4252 Manuals

The ADF4252 is a dual fractional-N/integer-N frequency synthesizer from Analog Devices. It operates from a 2.7V to 3.3V supply voltage and features a programmable dual modulus prescaler, programmable charge pump currents, a 3-wire serial interface, digital lock detection, a power-down mode, and a programmable modulus on the fractional-N synthesizer. ADF4252 can be widely used in mobile radio base stations (GSM, PCS, DCS, CDMA, WCDMA), wireless handsets (GSM, PCS, DCS, CDMA, WCDMA), wireless LANs, communications test equipment, and CATV equipment.

The ADF4252 is a frequency synthesizer from Analog Devices. It is powered by 2.7V to 3.3V and supports 3.0GHz fractional-N/1.2GHz integer-N. It supports 4/5, 8/9, 16/17, 32/33, 64/65 pre-divider ratios, 8/9, 16/17, 32/33, 64/65 programmable charge pump currents, three-wire serial interface, digital lock detect, power-down mode, programmable modulus on fractional-N synthesizer, trade-off noise versus spurious performance
