Part Number: LMK00308
we need a clock buffer/mux which is able to multiplex two input and fan out 8 output . One of the input signals is LVDS(0-1000MHz), the other is analog sine-wave(0-100MHz). The output signal should be LVDS. LMK00308 looks nice, we want to know if it can support sine-wave input or is there any recommendation on how to make it work. Thanks!
Yes, you can apply a sine-wave input through an AC coupling capacitor to the OSCin input pin (leave OSCout pin floating).
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to haopeng han:
1 to 2 Vpp swing is the suggested range, and higher swing/slew rate is recommended for better performance.
For a sine-wave with input, OSCin performs better than CLKin up to about 150 MHz In terms of additive phase noise/jitter.
If the single-ended input slew rate is faster than 2 V/ns, then CLKin will perform better than OSCin.
