TLV320ADC3101: PPS framwork supported sampling frequency

Part Number: TLV320ADC3101

Dear expert,

I am using the PPS for develop the processing flow, from the help manual, I found that the 4X decimation framework support only

48, 44.1, 32, 24, 16, 8 times of sampling frequency, but for me, I want to use 22.05KHz for fs, does it mean that I can not use such sampling frequency?

and I have to adjust the P R J D setting to make the result fs get to one of the listed fs Hz?

Hi,

The ADC3101 definitely supports a 22.05kHz sample rate, but let me confirm there aren't any issues programming the miniDSP for this rate!

Best,

Zak

Dear Zak，

thanks for your reply.

do you mean the manual is not updated and I can set 22.05K even I select the framework of 4x in the PPS ?

Hi,

Yes the help menu does not include every sample rate but within the properties in PPS you can select 22kHz.

Best,

Zak
