Hello again, friends!

We are going to replace CC1120 with CC1125 in a custom board where is implemented also the CC1190 extender. For the proper configuration of the radios, we use your software SmartRF Studio (v7), but we have now the problem that for CC1125 there is no options to configure the radio with the extender CC1190. Can we use the same register values that uses CC1120 with CC1190?

PS: other question about the replacing: I have read in this forum that, apart from the crystal (40MHz), it is necessary to place a 1.5nF capacitor instead of 1.8nF between the pins LPF0 and LPF1. Is this true?

Thanks in advance!

Best regards,

Luis

The settings for CC1120 + CC1190 can be used
