Hi all, the programming guide for CC1200 gives the symbol rate register definitions as shown.
However, the equations don't seem to check out; with the default SRATE_E value of 4 and the default SRATE_M value of 239914, the symbol rate comes out to be:
( (2^20 + 239914) * 2^4 * 40Mhz / 2^39 )ksps = 1500ksps which is well above the allowable limit of 500ksps.
What am I missing? Is the exponent signed or would it just max out at 500ksps or am I misunderstanding the equation?
Thank you for any help!
