ADF4355-2BCPZ

ADF4355-2 is a microwave wideband synthesizer with integrated VCO. It 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 4400MHz. It has an integrated voltage controlled oscillator (VCO) with a fundamental output frequency ranging from 3400MHz 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 radio frequency (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. It is used in application such as 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.
