  • Advanced PCB Layout Course, L4

    Hi,

    I have a question regarding Lesson 4:

    I understand activities for the Module. There are two project in L4 about this:
    L4-01-Setup Differential Pairs
    L4-02-Length Matching Differential Pairs-Module
    As I can see only difference between them is following: On L4-02 HDMI and PCI diff pairs are routed and length matched, but DQS signals for DRAM are length matched only on L4-01, but not on L4-02? LVDS diff pairs are length matched on both L4-01 and L4-02.
    As far as I understand, all signals should be length matched in order to pass to Lesson 5.

    Best regards,
    Milos

    You do not need to length match all - you can do some and when you feel confident, you can move to the next activity.
