Description

The ADF4355-3 allows the implementation of fractional-N orinteger-N phase-locked loop (PLL) frequency synthesizers whenused with an external loop filter and an external referencefrequency. A series of frequency dividers at the output provideoperation from 51.5625 MHz to 6600 MHz.The ADF4355-3 has an integrated VCO with a fundamentaloutput frequency ranging from 3300 MHz to 6600 MHz. Inaddition, the VCO frequency is connected to divide by 1, 2, 4, 8,16, 32, or 64 circuits that allow the user to generate RF outputfrequencies as low as 51.5625 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 ADF4355-3 operates with analog, digital, charge pump, andVCO power supplies ranging from 3.1515 V to 3.4485 V. TheADF4355-3 also contains hardware and software power-downmodes.Applications 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
