CDCLVP111-SP: The mean of Differential output voltage swing

Part Number: CDCLVP111-SP

Hi,

My customer is using CDCLVP111-SP.
Could you let me know the mean of Differential output voltage swing, please?

In datasheet, it shows 350mV as min.
Which case of below does this mean?

Best regards,
Shimizu

    Hi Shimizu

    I believe the answer is Case 3 shown below.  The 350mV spec is actually 350mVpp-diff.  This is in line with Figure 4 which shows the minimum VOD to be 175mV-diff at 3.5GHz which is 350mVpp-diff.  To avoid confusion, I think this graph should be plotted with the same units as the spec - mVpp-diff. I will confirm with the apps engineer that supports this device who returns to the office on Tuesday.

    Regards,

    Christian

    Hi Christian,

    Thank you for your support at previous question.
    I add a question about figure 4 in datasheet.

    The characteristcs curve of Figure 4 is informaton at Vcc = 2.375V.
    Is this characteristcs curve up or down by Vcc = 3.3V?
    We want to know the trend of curve by Vcc.

    We want to know your opinion as just reference.

    Best regards,
    Shimizu

    Shimizu,

    I agree with Christian's interpretation of the datasheet.Increasing VCC will increase output VOD.
