CC2541-Q1: about Gaussian filter BT

Part Number: CC2541-Q1
Other Parts Discussed in Thread: CC2541

Hi TI Experts,
My customer has a question for 1Mbps GFSK of CC2541.

- What is the BT value of Gaussian filter used in CC2541 proprietary mode GFSK?
- Can they disable for gaussian filter? They would like to know how to disable for it, if they can disable.

Best Regards,
Yojiro

What is the background for the question? I believe BT = 0.5 on CC2541

25.6 in www.ti.com/.../swru191f.pdf list the available modulation formats.

Hi TER,

Thank you for kindly support.

Because they want to measure the radio performance with spectrum analyzer.

What mean "believe", do you not have the correct value?

In the bluetooth specification, the GFSK BT = 0.5.
I think so the BT = 0.5 on CC2541's bluetooth mode.
is the GFSK BT same as in the proprietary mode?

Best Reards,
Yojiro

Use BT=0.5. The BT is the same independent of mode.
