Does 9160 need a 32kHz crystal for LTE modem operation

[RvB]

Hi,

we are confused:

The PS of the 9160 has the single  Note: The LTE modem requires use of LFXO as the LFCLK source.

But looking at the reference schematics for the 9160 DK, there is no 32kHz crystal. 

So question is of I can do an LTE connection without a 32kHz crystal?

thanks

Hi,

 

LFXO is included inside of the nRF91 SiP.

 

Kind regards,

Hi, thanks for the quick answer. Where should I have found this? I hate it when I ask questions which are actually RTFM....

Hi!

 

Happy to help out.

There's a section in the first page, where it states that "All necessary clock sources integrated", and you can see it in the block diagram as well:

Kind regards,
