Bruce li

Part Number: CC1310

Dear TI Expert,

My customer is using 1.5mbps data rate 4FSK mode on CC1310 @433M, they want to know the RF detail parameters about 4FSK mode, especially bandwidth. Could you kindly give some advice? Thanks a lot.

Hi Bruce,
If you are using the typical test case 4FSK example then following are the parameters:
- 4byte preamble
- 4byte sync
- 750ksps
- 150khz deviation (inner symbol)
- 1.56MHz rxBW
- 650kHz RX IF bandwidth

Bruce,

It would look like this. Approximately 1MHz wide with a flat top.
