ADF4355BCPZ

ADF4355 is a microwave wideband synthesizer with integrated VCO. This device allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference frequency. A series of frequency dividers permits operation from 54MHz to 6800MHz. The ADF4355 has an integrated VCO with a fundamental output frequency ranging from 3400 MHz to 6800 MHz. 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 radio frequency (RF) output frequencies as low as 54 MHz. For applications that require isolation, the RF output stage can be muted. The mute function is both pin and software controllable. It is widely used in application like wireless infrastructure (W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, DECT), point to point/point to multipoint microwave links, satellites/VSATs, test equipment/instrumentation, clock generation etc.
