Hi dear supporting team,

do we have one clk buffer (better 1 to 2) that could have similar output swing @ 3GHz as ADCLK925? TKS!

Hi Vera,

The CDCLVP215 that you listed should work- the minimum differential voltage swing of the CDCLVP215 is 600mV vs the ADCLK925, which has a minimum swing of 610mV. Unfortunately we do not have anything with fewer outputs- the only clock buffers that support up to 3.5GHz all have more than 2 outputs.

Regards,

Hi Tim,

I think CDCLVP215 could not support 600mV at 3GHz, as the plot in the d/s, the output swing dropped a lot at high frequency.

Hi Vera,

I took a look again at all our buffer products that support an output frequency of over 3GHz- unfortunately all of them have differential output swing below 600mV at 3GHz.
