CC1101: Custom Freq for 920 MHz

James Ee

Part Number: CC1101

What code should I set for FREQ2, FREQ1, FREQ0 for carrier frequency 920 MHz?

Understand that SmartRF Studio can do the calculation, but it only run on Window platform. I do not have a Window machine.

May I trouble someone who have installed SmartRF Studio to assist. Many thanks in advance

See section 21 in http://www.ti.com/lit/ds/symlink/cc1101.pdf for a equation you can use. But note that you get other register settings from SmartRF Studio that you need.

I believe it's possible to install Studio in a virtual machine, have you looked into this option? Since you don't need access to the USB ports for just getting the settings this should work.

Hi TER

Thanks for the info.

// Carrier frequency = 923 MHz

#define F2_923 0x23

#define F1_923 0x80

#define F0_923 0x00

// Carrier frequency = 920 MHz

#define F2_923 0x23

#define F1_923 0x62

#define F0_923 0x76

I have manually worked out the code. Pasted here in case someone faced the same problem as me.

Regards,
