Lowest Phase Noise PLL Synthesizer using Fractional-N Technology
Analog Devices Inc.
Description
The ADF4252 Fractional-N Synthesizer when combined with a VCO and loop filter forms a complete phased locked loop (PLL). This solution from ADI creates state-of-the-art LO's (local oscillator) for...
Features
Sigma-delta based fractional-N technology ensures superior Phase Noise and spurious performance is maintained over temperature Flexibility of programmable fractional-modulus ensures exact output frequencies can be synthesized. 0.1 - 3.0GHz Fractional-N / 0.05 - 1.2GHz Integer-N PLL's 3 wire Serial Interface with 1.8V logic compatibility 250MHz REFin Frequency 8 x Programmable charge pump currents PFD frequencies up to 30MHz allow faster settling and lower phase noise. Supported on ADIsimPLL software design tool Available in 4x4mm Chipscale package 2.7 - 3.3V Power Supply with separate Vp to 5V
