I tried to look for that part you had mentioned but I cannot find it, I will continue to search for it howeverRaTTuS wrote:awesome!
you can get 5 port nic solutions
i.e. 4x 100mbps with a 1g uplink port [all on one chip]
I forget the model number but have posted before
I do actually use a 4 layer board it just doesn't show it in the Pictures because I turned off the middle layers so that it is clearer for everyone to seeamk wrote:Why use a two layer board? This sort of circuitry requires good signal integrity for the high speed signals and a low impedance (low for high frequency) power distribution network. Such a board will probably radiate to much and be too susceptible for exteranal noise sources. I would at least use a 4 layer board, you can use the internal planes for low impedance power distribution, shielding/cancelation and return path. Use a thin pre-preg between the internal layer and the top layer so you can easy design the right controlled impedance traces for USB, HDMI and Ethernet. This will greatly benefit signal integrity and give much better EMC behaviour, at only little extra cost.

is one that I found
this is something that I would consider kickstarted ;-p
I have a question...amk wrote:Why use a two layer board?
