ADF4355-2BCPZ

IC INTEGRATED SYNTH/VCO 32LFCSP Clock Generator 10MHz to 500MHz Input 4400MHz Output 32Pin LFCSP EP Tray

The is a fractional-N or integer-N phase-locked loop PLL Frequency Synthesizer when used with an external loop filter and an external reference frequency. A series of frequency dividers permits operation from 54 to 4400MHz. The ADF4355-2 has an integrated VCO with a fundamental output frequency ranging from 3400 to 6800MHz. In addition, the VCO frequency is connected to divide by 1, 2, 4, 8, 16, 32 or 64 circuits that allow the user to generate RF output frequencies as low as 54MHz. For applications that require isolation, the RF output stage can be muted. The mute function is both pin and software controllable. Control of all on-chip registers is through a simple 3-wire interface. The ADF4355-2 operates with analog and digital power supplies ranging from 3.15 to 3.45V, with charge pump and VCO supplies from 4.75 to 5.25V. The ADF4355-2 also contains hardware and software power-down modes.
