 The phase-noise specified in Section 1.3 is referenced to the phase frequency detector (PFD) at 1 Hz. To convert that to the noise measured on the actual beat-note, it must be rescaled with the following formula: The phase-noise specified in Section 1.3 is referenced to the phase frequency detector (PFD) at 1 Hz. To convert that to the noise measured on the actual beat-note, it must be rescaled with the following formula:
  
-<WRAP center round box 450px> **D2-135 Phase-Noise Floor = -213 + 20Log(N) + 10Log(F<sub>REF</sub>)**</WRAP>+<WRAP center round box 450px> **D2-135 Phase-Noise Floor = -213 + 20Log(N) + 10Log(ƒ<sub>REF</sub>)**</WRAP>
  
-where N is the value of the divider and F<sub>REF</sub> is the reference frequency as measured in Hz.
