Overview
Data Sheet Microwave Wideband Synthesizer with Integrated VCO ADF4355-2 FEATURES GENERAL DESCRIPTION RF output frequency range: 54 MHz to 4400 MHz The ADF4355-2 allows implementation of fractional-N or Fractional-N synthesizer and integer-N synthesizer integer-N phase-locked loop (PLL) frequency synthesizers High resolution 38-bit modulus when used with an external loop filter and an external reference Low phase noise, VCO frequency.
A series of frequency dividers permits operation Programmable divide by 1, 2, 4, 8, 16, 32, or 64 output from 54 MHz to 4400 MHz.
Analog and digital power supplies: 3.
3 V Charge pump and VCO power supplies: 5 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 The ADF4355-2 has an integrated voltage controlled oscillator (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 radio frequency (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.
APPLICATIONS Control of all on-chip registers is through a simple 3-wire interface.
Wireless infrastructure (W-CDMA, TD-SCDMA, The ADF4355-2 operates with analog and digital power supplies, WiMAX, GSM, PCS, DCS, DECT) ranging from 3.
15 V to 3.
45 V, with charge pump and VCO Point to point/point to multipoint microwave links supplies from 4.
75 V to 5.
25 V.
The ADF4355-2 also contains Satellites/VSATs hardware and software power-down modes.
