Original question:

AM5746: QSPI ; clock mode 3

AM5746: Limited wiring length limit for qspi_clk

Part Number: AM5746

Hi Support Team,

Please reply to the following question from our customer.
*******
The wiring length of Qspi1_sclk on the current board is approximately 11 cm,
and we have decided to modify the wiring length at the time of revision.
We would like to do the modification without modifying the wiring length
as much as possible due to the busyness of other wirings.

Q1: In the AM574x Datasheet guideline, I think the recommended value
including the margin is stated, so please tell us the limit value of wiring length
for Qspi1_clk. (Time order is also acceptable).
Note that we do not use qspi1_rtclk.

Best regards,
Kanae

    Hi Support Team,

    I have not been able to get any reply at all. Does this mean that as a manufacturer,
    you can only provide recommended values, but cannot disclose the limit values?
    If so, please post your comment that "as a manufacturer, we cannot disclose the limit values"
    because we need to explain this to our customers.

    Best regards,
