i.MX 6DQ Synchronous Display Interface setup/hold Timing?

[t-iishii]

Hello Artur,

In thred https://community.nxp.com/thread/382105 and https://community.nxp.com/thread/446848,

We discuss about data setup and hold timing parameter about Synchronous Display Interface.

To understand IP18(Data setup time) and IP19(Data holdup time) parameter in Table 70 of datasheet(IMX6DQAEC),

It will confusion because it has two parameter both rise and fall edge in one table.

The other hands, to design a timing for LCD, only one edge need to attention.

So, attached documents that I create a separate tables for each edge.

How do you think my understanding about this parameters?

Best regards,

Ishii.

Actually, both IP18 and IP19 parameters are referenced to the same clock edge (either rising or falling depending on the clock polarity settings), so, everything looks good on your diagram.

Have a great day,
Artur

Hello

I modify attached timing document based on the datasheet timing Figure 71.

Please review a document and give me a comment for that.

Best regards,

Ishii
