Hi
When manually setting Gain for each of Luma / Chroma, the following formula is in the data sheet.
Please tell me about the design value when the ideal signal (NTSC @ CVBS) is input for [Calibration Factor] which is the denominator for Luma and Chroma.
Best regards

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 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,
Poornima
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
