ADF5355

Data Sheet Microwave Wideband Synthesizer with Integrated VCO ADF5355 FEATURES GENERAL DESCRIPTION RF output frequency range: 54 MHz to 13,600 MHz Fractional-N synthesizer and integer-N synthesizer High resolution 38-bit modulus Phase frequency detector (PFD) operation to 125 MHz Reference frequency operation to 600 MHz Maintains frequency lock over −40°C to +85°C Low phase noise, voltage controlled oscillator (VCO) Programmable divide by 1, 2, 4, 8, 16, 32, or 64 output Analog and digital power supplies: 3.3 V Charge pump and VCO power supplies: 5.0 V, typical Logic compatibility: 1.8 V Programmable dual modulus prescaler of 4/5 or 8/9 Programmable output power level RF output mute function Analog and digital lock detect Supported in the ADIsimPLL design tool 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 The ADF5355 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. The wideband microwave VCO design permits frequency operation from 6.8 GHz to 13.6 GHz at one radio frequency (RF) output. A series of frequency dividers at another frequency output permits operation from 54 MHz to 6800 MHz. The ADF5355 has an integrated VCO with a fundamental output frequency ranging from 3400 MHz to 6800 MHz. In addit...
