AWRL6432: How to change the ADC sampling time?

Jun Ito(AW)

Part Number: AWRL6432

Hi Team,

We saw ADC sampling time is 300ns in GPADC parameters of datasheet 9.4.2.

Is it possible to change the value from 300ns to the others?

If yes, could you please tell us the method how to change?

Best regards,

Ito

    Hey Ito-san,

    The ADC sampling time is determined by two parameters in the chirpComnCfg: DigOutputSampRate and NumOfAdcSamples. This can be calculated by taking the number of ADC samples and dividing by the sampling rate. Note: the DigOutputSampRate specifies the decimator to be used to determine the sampling rate (sampling rate = 100 MHz/DigOutputSampRate). For example, if DigOutputSampRate = 32 (Sampling Rate = 3.125 MHz) and NumOfAdcSamples = 128, then the sampling time is 40.96 ns (128/3.125 MHz).

    Regards,
