Hot-selling and scarce ADF4350BCPZ Wideband Synthesizer with Integrated VCO LFCSP32 spot stock

Product Descriptions

The ADF4350 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers if used with an external loop filter and external reference frequency.

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 16 circuits allow the user to generate RF output frequencies as low as 137.5 MHz. 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.

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