CC1312R: Bit Error Rate vs SNR

Koichiro Tashiro

Part Number: CC1312R

Hi,

My customer is asking BER vs SNR curve for CC1312/1310.
What customer wants is something like below figure.

Is this available somewhere?
If not, could you tell me how to measure it by themselves?

Thanks and regards,
Koichiro Tashiro

BER can be calculated from PER, see https://en.wikipedia.org/wiki/Bit_error_rate.

We don't have this as a function of SNR. But they can make a similar curve based on BER/ PER vs input signal strength vs packet length. BER/ PER increases as a function of packet length for the same input level.

Do you know exactly what they are going to use this for?

Hi TER,

Thanks for your quick reply.

Customer just wants to know CC1312/10 capability.
So parameters do not need to be BER vs SNR.

Below data are also fine.
- BER(PER) vs Eb/N0
- BER(PER) vs RSSI

Do you have such data for CC1312/10?

Thanks and regards,
Koichiro Tashiro

We don't have a curve as such.

The sensitivity limit given in the datasheet is set for 1 % BER. If the input signal increases by 2 dB, the PER will be 0 meaning that they can use the sensitivity numbers in the datasheet as a good indication on the chip's RF performance.
