Hot-selling and scarce ADF4350ABCPZ Wideband Synthesizer with Integrated VCO QFN32 spot stock

Product Descriptions

The ADF4350 allows implementation of fractional-N orinteger-N phase-locked loop (PLL) frequency synthesizersif used with an external loop filter and external referencefrequency.

The ADF4350 has an integrated voltage controlled oscillator(VCO) with a fundamental output frequency ranging from2200 MHz to 4400 MHz. In addition, divide-by-1/2/4/8 or 16circuits allow the user to generate RF output frequencies as lowas 137.5 MHz . For applications that require isolation, the RFoutput stage can be muted . The mute function is both pin - andsoftware -controllable. An auxiliary RF output is also available,which can be powered down if not in use .

Control of all the on-chip registers is through a simple 3-wireinterface . The device operates with a power supply rangingfrom 3.0 V to 3.6 V and can be powered down when not in use .
