Normally, microstrips are used on the surface layer, but striplines can also be used. If you're designing a network switch with high port count, the controller ICs may have a BGA footprint, so you'll need an escape routing scheme. Normally dog bone fanout is fine; the pitch on these components is not super-fine and you'll be … See more The routing requirements between the PHY chip and RJ-45 connectors involves groups of TX and RX lines routed as differential pairs, and these traces should be length matchedand symmetric. There is also a specific … See more There has been some debate as to whether Bob Smith termination is the best termination scheme for Ethernet routing. I've discussed this in a more recent article on my own site and here on Altium's PCB Design Blog.
