ddc264 linear breakout - ideas?

Hello DDC264 users.

Currently I try to do a layout with DDC264. All 64 channels have to be routed to a target left to right (not that unusual I think). I have routing ready but am not that happy with it despite it only requires two layers.

It looks like the IC designers had a distinctive idea how to place channels on the balls but I didn't catch it. Has anybody done similar layout and is willing to share a glimpse?

I have attached a picture of my actual layout test. What did I miss?

Regards, Stefan

PS: my application is very low speed, thus wire impedance is less important than isolation.

  • Hi Stefan,

    The channel sequences you are mentioning on the IC side are not directly output

    to be Channel1 to Channel64 sequentially.

    But the Data Output from DOUT signal will be always from Channel64 to Channel1 in sequence

    no matter how you place the wires in what kind of order.

    Thank you!

    Best regards,

    Chen

    Thanks for your feedback, Chen.

    With this topic I hoped to get a glimpse on some PCB layouts :)

    Hi Stefan,

    Here is the DDC264EVM user's guide attached.

    Please look at the EVM layout on the page#26.

    I can even send you the gerbers if you are interested.

    Please let me know.

    Thanks and best regards,

    Chen
