Gigabit Ethernet connector

I've certainly never heard of one. What makes you think one exists? Have you considered running a cable right to the board?

Hi All,

I´m designing a digital board in which I need a Gigabit interface over copper (1000Base-T).The problem is that I don´t have enough space for the RJ-45 connector, and I´m wondering if there exists other kinds of standard conector, smaller than RJ45.

Thanks!

You might try an SATA connector--it's not a lot smaller but it's flatter and the impedance is right. Just make sure you label it so that nobody tries to connect it to a disk or disk controller. A couple of the smaller Firewire connectors might work--Firewire is, I understand, 110 ohm, which should be close enough as long as you're not pushing the limit on cable length, but you'd need to use two of them as they're only two-pair. And good luck connecting a CAT5e cable to either.

Other than the RJ45 (and maybe the 110 punch block) there are no standards-compliant connectors for TP Ethernet. I'd say your only option would be to run a cable directly to the board, ensuring crosstalk, impedance, and other parameters are within spec.

What are you trying to fit this into that an RJ45 is too big?
