AM62P-Q1: connection of MCASP1_ACLKX

Part Number: AM62P-Q1

Tool/software:

Hello,

as below show, from D-note, should add a 22R at the output of MCASP1_ACLKX near to the SOC, but i do not find the resistor in the schematic of "PROC164E1-1_SCH_With_Design-Updates..Notes_V1.0", how to understand this?

thanks!

    Hello Liujian,

    The D-Note is not pointing to an existing resistor but rather recommends reserving a 0Ω resistor at the output of MCASP1_ACLKX near to the SOC and if you face EMI testing issues to swap the 0Ω with a 22Ω resistor.

    The resistor is mainly for smoothing the edge off the rising edge if it fails EMI testing.

    Let me know if this helps!

    Regards,
    Karam
