CDCLVD2106: Question regarding CDCLVD2106

Part Number: CDCLVD2106

Dear Team,

Can you please help with the following customer questions

1.    What is the current consumption?
Is it (Static supply current)+(supply current) = 45 + 177 = 222mA ?
2.    What is the additive jitter that I need to consider?
Is it 0.3ps RMS (as mentioned is table in page 5 in datasheet)? Or is it 171fs RMS (as mentioned is table in page 6)?
3.    What do I do with Vac_ref? what is its application?

Best regards,

Nir.

  • Hello Nir

    Here are the answeres to your questions:

    1. What is the current consumption?
    Is it (Static supply current)+(supply current) = 45 + 177 = 222mA ?
    A: Total Supply current is 177mA. You dont have to add 45mA again.
    2. What is the additive jitter that I need to consider?
    Is it 0.3ps RMS (as mentioned is table in page 5 in datasheet)? Or is it 171fs RMS (as mentioned is table in page 6)?
    A: 0.3ps is the max rms jitter over the PVT. Its a max datasheet limit. On page 6 are the two examples of rms jitter at two different frequencies and at typical conditions.
    3. What do I do with Vac_ref? what is its application?
    A: Please connect 0.1uF to ground.

    Best regards
