TDA4VM: Unable to enter PWL decompanding curve into DCC due to bit-depth limitations

Part Number: TDA4VM

Hello,

I'm attempting to use DCC V3.0 to tune a WDR camera pipeline. The camera sends 18 bits-per-pixel data that is companded to 12bpp and DCC only allows for 20-24 bit outputs.


I tried putting in the curve that matched the image sensor's PWL curve, up to 4094 but this trick did not work.

Any advice is greatly appreciated!

Best,
Clarke
