Fractional Spurs (Impact of Various Settings)
For these measurements, they were all taken at 2703 MHz with the same board, but various things were
varied to show the impact.
Default Setting
2
nd Order modulator, Fpd =20 MHz, Kpd=24x, PFD_DLY = 370 ps, Strong Dithering
This is the default setting which the following spur plots will be compared to. Compare this to the phase
noise plot for integer mode to see that the fractional circiutry can be set up to add no phase noise, just
spurs. The user has programmability to sacrifice phase noise for spurs. For the 2
nd order modulator, the
added phase noise is typically fairly low.
