Standard MicroZed Length Tuning.

Former Member
Former Member over 10 years ago

Dear Avnet Rep,

Having purchased a Microzed EVM and worked through the documentation I can ascertain that the board itself is 'trace length tuned' into pairs at least for the purposes of LVDS.

I would like to use the break-outs in a more 'standard' method of parallel GPIO to a high speed peripheral.

As an 'example', though I know there is already DDR on board, imagine for illustrative purposes that I wanted to connect the breakouts to an additional, external breakout board module.

Thus my question, is there any information on, besides the pairs, over all what sets of connections on the breakout are equally length tuned ? Are they all of equal length, or only in pairs ?

    Hello,

    I just posted the MicroZed Rev G net length report. (should be visible in a few hours)

    You will need to include the internal package delays for the 7Z020 device yourself.

    Thanks,

    Josh

    Perfect - thanks very much, and thanks for clarifying the internal delays too.
