Input capacitance of the CC1175

Please tell me the input capacitance of EXT_OSC of CC1175.

Also, is it possible for you to present the equivalent circuit?

Our customers

Our customer is considering to use 10 [kohm], 10 [pF] TXCO with 22 [pF] for DC cut capacitor.

Here is a thing of the same specs and reference design of CC1175.

Do you have any advice?

best regards,

I do not know the input capacitance of EXT_OSC, but 10 [kohm], 10 [pF] TXCO with 22 [pF] for DC cut capacitor is the same spec as the EPSON (TG5021CG) and NDK (NT2016SA) TCXOs we use so your customer should go ahead and use this TCXO.

Hi, Sverre.

Thank you for reply.

Our customers can use the TCXO of similar spec and EPSON (TG5021CG) and NDK (NT2016SA),
Is it may be considered that there is no problem?

Yes, they can use a TCXO with similar spec to the TCXOs that we use.
