CC2651R3: 32kHz crystal oscillator input

Part Number: CC2651R3

Tool/software:

Hello,

Can we use external oscillator for LF Crystal Oscillator input (X32K_Q1, X32K_Q2)?or only crystal?

We want to use Crystal Oscillator such as below

If it can, which (X32K_Q1, X32K_Q2) can use for signal input?

Thanks,

In short, it is not supported.

The long answer is you can get it to work through several workarounds (like shorting one of the terminals and inputting a square for certain parts) and validation efforts, but it it may not be worth it.
