ADF4355 Datasheet Microwave Wideband Synthesizer

Manufacturer: Analog Devices

General Description

RF output frequency range: 54 MHz to 6800 MHz Fractional-N synthesizer and integer-N synthesizer High resolution 38-bit modulus 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 3-wire serial interface Analog and digital lock detect 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 ADF4355 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 54 MHz to 6800 MHz.

The ADF4355 has an integrated VCO with a fundamental output frequency ranging from 3400 MHz to 6800 MHz.
