Can the double-row pins with 1.27mm pitch carry gigabit differential signals? [Copy link]

1. I want to design a motherboard + baseboard, and I am considering using a 1.27mm pitch double-row pin header to connect the motherboard and baseboard. 2. One of the gigabit differential signals (from PHY) needs to be transferred from the motherboard to the baseboard. Can the 1.27mm pitch double-row pin header meet the needs of gigabit differential signals? Thank you!

There is no problem with the spacing of 1.27. I will look for the standard reference when I have time in the evening.

Refer to "【Communication Industry Standard】YDT1352-2005 Technical Requirements and Test Methods Standard for Gigabit Ethernet Optical Transceiver Modules" 7, Electrical Interface Classification, Pin Definition and Electrical Performance Parameters Electrical Interface Classification

Ordinary double-row pins are not enough. You can consider looking for high-speed sockets with a spacing of 1.27. This one is available.

It is OK if the connection is not long.
