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
