connector for LVDS

[Ian]

I've used SCSI2 connectors and commercial cables for differential PECL
over short distances, but differential prop delays (one wire of the
pair relative to the other) added jitter, on the order of 30-40 ps rms
over a meter or two of cable.

I've used SCSI2 commercial cables for LVDS at 100MHz with good success
(can't remember if it was 40 or 80 pairs). Worked to at least 10 metres
length.
I'm sure the headers were not vacuum tight at the connector end, but I think
the
junction between cable outer and connector body was pretty good.

Hello John,

We're paying $2.31 for the basic pcb-mount right-angle SMB. I hate
SMA's... you spend half your life screwing/unscrewing them.

That's a lot of cost. Once I talked a client out of them and into RCA.
It was kicking and screaming on the systems production side but in the
end they said that RCA is even easier on their fingers. Less blisters.

They wanted at least the cool looks so we opted for the gold plated RCA.
Connector costs still plummeted by about 10dB and now they can even have
color coding. White, red, yellow and black. That was really cool for the
folks who wear glasses. You can also stripe them with a Sharpie and in
contrast to SMB that won't rub off too much over time.

Regards, Joerg

Hello Rene,

What are RCA connectors ?

Those in the back of stereos etc. I think in Europe you call them Cinch
connectors. In Germany and Switzerland I also saw them listed as "US
NF-Stecker".

In the US they are even used for VCR signals because we do not have
SCART connectors.

Regards, Joerg

My aerospace guys are used to SMAs and SMBs, and would laugh us out
the door if we used RCAs. Besides, RCAs are too big for VME front
panels and the other stuff we do. But we sell a VME module for
somewhere between $4k and $12k, so two or three bucks per coax
connector is not a big deal.

True, in that environment it has to be king size. Once when I was
pondering the $25 or so for a multiplier on a project like that the guys
around me did start to laugh. The reason I pondered wasn't so much the
BOM total but the fact that the taxpayer ends up holding the tab for
much of that.

AKA "Phono Plug". They were designed by RCA to connect a phono
cartridge to an audio amp, or to a table radio.

I read in sci.electronics.design that Joerg

Not in UK, because someone owns the trade name 'Cinch'. We call them
'phono connectors'.

They're the worst coax plugs ever. The center connector makes contact
before the shield (how stupid is that?), which can make you lose your
hearing in certain circumstances.

Neutrik make one that doesn't do that.

You're not supposed to plug it into your ear.

John,

have you considered the 3M MDR cabling system?
They are designed for LVDS .

Interesting, except that the poster was interested in
single channels. I also called up the local cable and
connector guys once. They weren't interested in single
channel LVDS connectors. Apparently the market is
not considered big enough.
