9. Typical Phase Noise Plots
The following is a typical phase noise plot. The clock input source was a Rohde and Schwarz model SML03 RF
Generator. The spectrum analyzer was either an Agilent model E5052B, model E4400A or model JS-500. The
Si5315 operates at 3.3 V with an ac coupled differential PECL output and an ac coupled differential sine wave input
from the RF generator at 0 dBm. Note that, as with any PLL, the output jitter that is below the loop BW is caused by
the jitter at the input clock, not the Si5315. Except as noted, loop BWs of 60 to 240 Hz were in use.
