We want to use AD9513 for our product
We plan input sine wave or clipped sine wave to AD9513 from VCTCXO, is it OK? or have any other suggestions?
The AD9513 CLK inputs can be driven single ended ac coupled. The reference input is self biased to 1.6V so you will have to take care to make sure that the Vpp of your signal is than 3.3V as to not overdrive the receiver. You should also ac couple the unused reference input to ground. Please let me know if you have any further questions.
Thanks a lot for your reply.
By the way, we saw the "Input Sensitivity" is 150 mVp-p from datasheet.
Is it means the input signal should be greater than 150mV (signal swing > 150mVp-p)?
yes, exactly that is meant by the input sensitivity, but only the typ. value is given,
so you should make sure that your input signal is somewhat greater.
I'd like to add that this spec is about 1/4 of the LVDS spec, so even a low amplitude LVDS signal is sufficient to drive the input of the AD9513.
