Audio CODEC with Jetson TX2

Hello,

I was wondering with what audio CODEC device has NVidia tested the I2S lanes?
I am specially interested in audio CODECs that convert analog to I2S and I2S to analog, which datasheet is available.

Hi Igal,

We use the Realtek RT5658 codec to validate the I2S interface. We have tested both playback and capture with this codec and so both I2S to analog and analog to I2S have been tested. I have also tested the I2S interface by using one I2S as the master and another as slave.

With the L4T release 28.1, by default the I2S interface is connected to a dummy spdif s/w codec which is essentially a null codec that allows us to play a file to an I2S interface without having any physical codec connected. So using the release you should be able to play a file to the I2S interface as observed the pins are toggling as expected.

Jon,
thanks for reply.

I could not find any information while googling. I have also tried to look for the component on Realtek site http://www.realtek.com/products/ but could not find any information related to the component.
Do you know where I can find information on the component and whether it has an Industrial Grade version?

BTW, are ALC5658 and RT5658 the same?

Hi Igal,

I recommend that you ask realtek if they have a variant that support industrial temp.

Yes the ALC5658 and RT5658 are the same thing. The Linux kernel driver [0] source file is called rt5659.c.
