PCM5122: purepath process flow to generate a tone / pcm5122EVM

Part Number: PCM5122
Other Parts Discussed in Thread: PUREPATHSTUDIO, , PCM5142,

Hi Team,

Could you please provide a basic process flow PurepathStudio example in order to generate a tone when using a PCM5122EVM?

Please provide a *.pfw file and we will change its parameters in order to generate a tone with our project specifications (frequency, amplitude, etc...).

Hi Marcos,

I will give this a try. I am not sure if the PCM5122 support this, you may need to use the PCM5142 as it supports custom process flows.

Thanks!
Paul

Also important to highlight that we want to send tone generated to the DAC output.

Hi.

What could be the best way to test pcm5122evm-u so generate and amplitude and frequency with less delay group as possible ? There is a mode which offers 1.2.TS.

Thanks in advance!!

Hi,

There is no problem on switching to PCM5142 since we are using PCM5122/42EVM-U evm. Please provide tone generator example.

Hi Marcos,

Attached is the tone generator example. The component in the flow allows you set the amplitude and frequency.

Thanks!
