Part Number: LM98620

Hello guys,

One of my customers is evaluating LM98620 on their own board.

The device is work well basically.

But the output data from LM98620 doesn't keep 255d when CCD sensor is saturated by very bright light.

Often 250d, 251d, 252d are read out.

Is there any way to keep 255d when CCD sensor is saturated by very bright light?

Best regards,

Kazuya.

Hi,

Thank you for your question.

I understand customer is looking for keeping 255d however LM98620 does not have the way or such a function.

Hello guys,

I am the engineer who asked the question.

When saturated, Odd or Even is 251d and one is 255d.

This issue occurs in RGB.

It also occurs when the sampling timing is not changed and only the gain is increased.

Do you have any register settings or hints for improvement?

Best regards,

Masaaki.
