ADF4350BCPZ

ADF4350 is an implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizer. It is used with an external loop filter and external reference frequency. It has an integrated voltage controlled oscillator (VCO) with a fundamental output frequency ranging from 2200MHz to 4400MHz. In addition, divide-by-1/2/4/8 or 16 circuits allow the user to generate RF output frequencies as low as 137.5MHz. For applications that require isolation, the RF output stage can be muted. The mute function is both pin- and software-controllable. An auxiliary RF output is also available, which can be powered down if not in use. It is used in application such as wireless infrastructure (W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, DECT), test equipment, wireless LANs, CATV equipment, clock generation etc.
