Other Parts Discussed in Thread: PMP40286

Hi team,

I have a question about CC line layout recommendation below. 

"Keep the CC lines close to the same length."

What is the purpose of controlling the length of each CC lines? 

If there is a need to keep it same length, could you give me the max tolerance?

regards,

    Hi Tsuji-san,

    Actually we don't have this specific data, but I measure our reference design PMP40286, and their length are the 255.534mil(CC1), 547.526mil(CC2), so I guess about 300mil difference is ok.

    And I also attached the layout document here, you can refer to it.

    Best Regards,
