ECNR in IMX8

M8 — Mon, 08 Jan 2024 07:26:47 GMT

Hi,

1. Do all i.MX8 processors (i.MX8 mini including) support ECNR?

2. Also does i.MX8Mini support LPCM (Linear Pulse Code Modulated Audio), OPUS, AAC-LC (Advanced Audio Coding Low complexity), Mixer?

3. Is USB role switch supported in i.MX8 mini? What's the rated USB current for this processor?

Thanks

Hi,

Thank you for your interest in NXP Semiconductor products,

1. This solution is for 8 family, not 8M Mini family (MIMX8QM5AVUFFAB, MIMX8QM5CVUFFAB, MIMX8QM6AVUFFAB, MIMX8QM6CVUFFAB, MIMX8QP5AVUFFAB, MIMX8QP5CVUFFAB, MIMX8QP6AVUFFAB, MIMX8QP6CVUFFAB.)

But there is this solution tested on 8MM that features AEC.

2. They are tested under android (three of them).

3. It has two OTG interfaces compliant to.

For a detailed current consumption description refer to datasheet.

Regards

Hi Joseph Linares,

Thank you for the details.

A follow-up question on USB current rating..

I am interested to understand what modes can be supported in USB - SDP/CDP/etc? Per my understanding SDP requires 100mA and CDP is up to 1.5A. But based on the datasheet (table 63), the current output of the USB seems to be too low.. Should I be referring to any other data?

Thanks

Hi,

They are not supported per se, you may want to refer to

14.8 USB Device Charger Detection Module (USBDCD)

From reference manual.

BC1.2 Spec is supported on 8M series (8M, 8MP, 8MN, etc).

Regards,
