Gigabit Ethernet connector |
|
|
Hi All,
I need to find a standard gigabit connector (1000BaseT) smaller than the
RJ45, is there any?
Itīs driving me almost crazy finding one!!
Thanks!

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? |

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

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.

| Is that any help if you try a integrated magnetics/RJ45 connector? |

Hi again!
Sorry, but Iīve been out for a while.
At the end, the solution that Iīve taken is using a low-profile RJ45. It is for a mezzanine card, and the design is heigth critical, but after studying the case for 3 weeks, I think we can reduce the board around 0.5mm and use it.
Thanks for your help! |
