ADF4150

Data Sheet Fractional-N/Integer-N PLL Synthesizer ADF4150 FEATURES GENERAL DESCRIPTION Fractional-N synthesizer and integer-N synthesizer Programmable divide-by-1/-2/-4/-8/-16 output 5.0 GHz RF bandwidth 3.0 V to 3.6 V power supply 1.8 V logic compatibility Separate charge pump supply (VP) allows extended tuning voltage in 3 V systems Programmable dual-modulus prescaler of 4/5 or 8/9 Programmable output power level RF output mute function 3-wire serial interface Analog and digital lock detect Switched bandwidth fast-lock mode Cycle slip reduction APPLICATIONS The ADF4150 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers if used with an external voltage-controlled oscillator (VCO), loop filter, and external reference frequency. The ADF4150 is for use with external VCO parts and is software compatible with the ADF4350. The VCO frequency can be divided by 1/2/4/8/16 to allow the user to generate RF output frequencies as low as 31.25 MHz...
