Hi !

 

I have some question about ADV7182 RSD.

I already asked about this in past and sorry to ask again but if you can help us , it will help our customer .

 

*******************************************************************************************************************************

 

Q1)

ADI added 3.1.3 at the RSD.

Is this additional limitation?

Can you explain why ADI added this?

↓Rev.C

*******************************************************************************************************************************

 

Q2)

3.2.2 is added at the RSD.

With my understanding , when our customer use ADV7182 with Diff-Input,

they should set 0x00 = 0x10 and after that they should set the INSEL[4:0].

Is my understanding correct?

What will happen if they don't set 0x00=0x10 before they select INSEL[4:0]?

The lock time will be very long?

Q3)

3.2.3 is added at the RSD.

Why did you added this at RSD?

What will happen if our customer don't set these setting?
Lock time is only the impact?

I think this was already in the old EVAL board script so this won't be a problem.

Q4)

At 3.3.1 you changed two kind of things.

Why did you change these?

What if our customer don't write 42 60 A0 and don't waite 25ms?

At the old RSD this is not written so our customer don't do this in their unit (it is already Mass production few years ago).

↓Rev.C

*******************************************************************************************************************************

 

Q5)

At 3.3.1 and 3.3.2 , setting is separated.

Which is the first one that our customer have to set up?

At the Eval-board 3.3.1 => 3.3.2 is written so I think this is correct.

Also at the old RSD , the setting is different.

What will happen if our customer are using the old setting

↓Rev.B

*******************************************************************************************************************************

 

Q6)

At 3.4 ADI changed the sequence.

The old one in the EVAL-board script is this.

-----------------------------------------------------

  42 0E 80 ; ADI Required Writes
  42 D9 44 ; ADI Required Writes
  42 0E 00 ; ADI Required Writes
  42 0E 40 ; Select User Sub Map 2
  42 E0 01 ; Select fast Switching Mode

-----------------------------------------------------

Why did ADI change the sequence?

What will happen if our customer use the old sequence?

↓Rev.C

 

*******************************************************************************************************************************

 

Q7)

At 3.5 ADI changed the sequence.

The old one in the EVAL board script is this .

-------------------------------------------------------------

42 03 0C ; Enable Pixel & Sync output drivers
42 04 07 ; Power-up INTRQ, HS & VS pads
42 13 00 ; Enable INTRQ output driver
42 17 41 ; select SH1
42 1D 40 ; Enable LLC output driver

-------------------------------------------------------------

Why did ADI change the sequence?

What will happen if our customer use the old sequence?

↓Rev.C

Q8)

At 4.1, ADI added one script.

Why did ADI added this?

What will happen if they don't do this?

↓Rev.C

*******************************************************************************************************************************

 

Q9)

At 4.2 and 4.3 ADI added some document that it was not written at RSD Rev.B.

Why did ADI added this?

↓Rev.C

Sorry for asking many many question about this.

But it is very important to understand what you changed because we have to explain everything to our customer at JAPAN.

So if you can make the revision history with the reason you changed , it will very useful for everyone.

It is very difficult work for us to check all documents that you updated.

We want to know more detail what you changed. More than revision history.

I think if you can share about that (maybe only to Distributor will be good) , it will be very useful.

 

Best regards,

Kawa
