CDCLVP111-SP: WCA help

Part Number: CDCLVP111-SP

Team, 

Working through some WCA at one of my designs and was hoping you could help me get the below information clarified. 

  1. Is there a spec for deterministic jitter, either in rms or peak-to-peak? I see the plots in figure 14 and 15 of the datasheet which look promising for only random noise.
  2. What is the bandwidth used for stated in note C on page 7 of the datasheet? Was this for the jitter measurements or?
  3. Can you provide PSRR data for this device?

    1) Is there a spec for deterministic jitter, either in rms or peak-to-peak? I see the plots in figure 14 and 15 of the datasheet which look promising for only random noise.
    [CY] There is not a separate spec for deterministic jitter. However, I recall that integrated jitter did not change when including spurs in the spectrum.

    2) What is the bandwidth used for stated in note C on page 7 of the datasheet? Was this for the jitter measurements or?
    [CY] After reviewing the datasheet, it seems this note is an error as there is not reference to it and, further, the jitter spec in Table 6.7 contains the frequency and bandwidth over which the spec was determined. We will have this corrected upon the next datasheet revision.

    3 )Can you provide PSRR data for this device?
    [CY] We do not have PSRR data for this device.

    Thanks
