AFE5809EVM: Sampling rate per channel

Sajad Rahmdel

Part Number: AFE5809EVM
Other Parts Discussed in Thread: AFE5809

Hello,

We're using AFE5809EVM and TSW1400 in our new sonar system. I would like to know the sampling rate for each channel of the AFE5809EVM. As far as I can see in the manual, the sampling rate is 65 MSPS for each channel. Is that correct? I'm trying to calculate the distance to the received echo of the object.

Thanks

Hi Sajad,

The AFE5809's sampling rate is specified on Page 15 of the datasheet as shown below.

Sincerely,

Olu

Olu,
As always thank you for your help.
What is the default value of the sample rate and where can I set it? Is the sample rate constant during the capture, or it is variable?

Hi Sajad,

To change the sample rate of the ADC, all you have to do is change the frequency of the input clock to the device (CLK_ADC).

Sincerely,
Olu
