With suggested application areas including wireless infrastructure (W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, DECT); test & measurement instrumentation/equipment; point-to-point or point-to-multipoint microwave links; satellites/VSATs; and clock generation, 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 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.
Control of all on-chip registers is through a simple 3-wire interface. The ADF4355 operates with analogue and digital power supplies ranging from 3.15V to 3.45V, with charge pump and VCO supplies from 4.75V to 5.25V. The ADF4355 also contains hardware and software power-down modes.
