Part Number: PCM2903C
Other Parts Discussed in Thread: PCM2903

Hello team,

I want to use PCM2903C to achieve that LINE-in AUDIO INPUT, across the PCM2903C, then USB as output connect the Vehicle Head Unit play audio.

1. So can you help to comment if the PCM2903 can support to translate the AUX signal to the Vehicle Head Unit.

2. If the PCM2903 can't support, which part will be a good choice.

Thank you.

Hi BR Vincent,

Yes the PCM2903C can support a line input to USB, which includes a signal from a typical AUX cable (3.5mm)

Best regards,
