(ADV7182A) About manual gain

Hi.

Can anybody give me some advice?

I want to know the value for "Luma calibration factor" and "Chroma caliblation factor"  for ADV7182A as soon as possible.

Best regards

Kawa

Hi Can somebody give my advice for this?

Hi Kawa-San,

 As already stated, ADV7182A Chroma/Luma Manual Gain are provided in (www.analog.com/.../ADV7182A.pdf -Page34/35), but there is no range provided to calculate the calibration factor.

Please note that in ADV7184/ADV7188 datasheet they have provided separate formula for calculating NTSC/PAL Luma/Chroma gain https://www.analog.com/media/en/technical-documentation/data-sheets/ADV7184.pdf in Page 36.

For Chroma Manual Gain please refer ADV7188 datasheet in Page38.

Thanks,

Hi 

Thank you for your support.

Sorry, I couldn't understood 100% what you are saying about.

Is it impossible to give us these two value?

1) Luma calibration factor

2) Chroma caliblation factor

Hi,

 We need to calculate the Luma and Chroma calibration factor from our side using the procedure which is provided in the ADV7182A datasheet at Page 34 and 35.

Hi 

Thank you for your reply.

So you mean this one?
