TDA4VM: H3A Configuration for a sensor with 3840 width

Todor Katsarski

Part Number: TDA4VM

Hello E2E,

We are working on the integration of a sensor driver which has 3840x2160 resolution. The H3A engine's documentation describes the following limitation:
Maximum input size is 2816 pixels.

How should we proceed with the configuration of the H3A engine for this sensor?

Best regards,
Todor

Todor,

H3A can handle up to 4096 pixels. Can you please point out the document and section number which says "Maximum input size is 2816 pixels"?

Regards,

Mayank

Mayank,

This is described in the TRM in section 6.10.4.3.4.6.1 RAWFE H3A Overview. Perhaps the limitation described there is not up to date?

Best Regards,
Todor

Hi Todor,

It seems like you have an old revision of the datasheet. I checked that it is correctly documented in the latest revision.

Hi Mayank,

Thank you for the support, our document's revision was indeed an older one.
The reason we are asking is because we faced some issues with configuring the H3A engine for this resolution. We will further report the exact configurations we used and what was the result after we are fully done with the configuration.

Best Regards,
Todor
