STW81100

Note 1):

Phase Noise SSB.

VCO amplitude set to maximum value [11].

The phase noise is measured with the Agilent E5052A Signal Source Analyzer.

All the closed-loop performances are specified using a Reference Clock signal at 19.2 MHz with phase noise of -141dBc/Hz

@1KHz offset and -146dBc/Hz @10KHz offset. All figures are guaranteed by design and characterization.

Note 2):

Normalized PN = Measured PN - 20log(N) - 10log(fcomp) where N is the VCO divider ratio (N=B*P+A) and fcomp is the compar-

ison frequency at the PFD input
