Description

The ADF4351 allows implementation of fractional-N or integer-Nphase-locked loop (PLL) frequency synthesizers when used withan external loop filter and external reference frequency.The ADF4351 has an integrated voltage controlled oscillator (VCO)with a fundamental output frequency ranging from 2200 MHz to4400 MHz. In addition, divide-by-1/-2/-4/-8/-16/-32/-64 circuitsallow the user to generate RF output frequencies as low as 35 MHz.For applications that require isolation, the RF output stage can bemuted. The mute function is both pin- and software-controllable.An auxiliary RF output is also available, which can be powereddown when not in use.Control of all on-chip registers is through a simple 3-wire interface.The device operates with a power supply ranging from 3.0 V to3.6 V and can be powered down when not in usApplications Wireless infrastructure (W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, DECT) Test equipment Wireless LANs, CATV equipment Clock generation
