Tool/software:

Hello team,

My customer would like input AC-coupled single-end clock to this device. (They can't use DC coupled)

How should I configure the input to CDCLVP1102?

I am thinking as figure below. Could you please check it?

Best Regards,

Kuwahara-san,

This figure looks good - the only suggestion I can make is putting a 50 Ohm resistor between VAC_REF and CLKP, in order to avoid connecting CLKP directly to that bias voltage.

Thanks,

Michael

Hello Michael-san,

Thank you for checking.

Should I place the 50 ohm resistor close to the driver or receiver (CDCLVP1102)?
