产品详情

The ADF5356 allows implementation of fractional-N or integer Nphase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference frequency. Thewideband microwave VCO design permits frequency operationfrom 6.8 GHz to 13.6 GHz at one radio frequency (RF) output. A series of frequency dividers at another frequency output permitsoperation from 53.125 MHz to 6800 MHz.

The ADF5356 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 53.125 MHz. For applications that requireisolation, the RF output stage can be muted. The mute functionis both pin- and software-controllable.

Control of all on-chip registers is through a simple 3-wire interface.The ADF5356 operates with analog and digital power suppliesranging from 3.15 V to 3.45 V, with charge pump and VCOsupplies from 4.75 V to 5.25 V. The ADF5356 also containshardware and software power-down modes.
