Single TCXO For Multiple ICs

Dear all,

I am designing a PCB with AT86RF215 RF transceiver and I want to use an external TCXO. The datasheet states that to use a TCXO de input should be clipped sine wave and the peak-to-peak voltage should be between 600mV and 1600mV. My problem is that I want to connect this TCXO to 2 different AT86RF215 ICs.. Given that both ICs are far away in the PCB, I think is not reasonable to connect the TCXO directly to ICs without some sort of buffering. Thus, I was thinking of using a simple buffer to output 2 signals with TTL level of 1.8V that would then connect to each IC.. Anyone has any suggestion or a better approach for this?

Thank you all for your time.

Kind regards

Use a "fanout buffer".

a buffer makes sense, since ICs sometimes output very strange noises from the clock input ports.

I would use a resistive divider at the end chip, and ac couple it with a voltage divider pair of resistors, if you want to satisfy that one chip's conditions.
