Hi,
I have a design where I have to route SATA signals from a main board to a
daughter board. The daughter board will likely have nothing except for the 7
SATA signals(4 data and 3 GND) connected to a regular SATA HDD connector
(unless some passives are needed?).
In my previous PATA design, I used a normal 44pin IDE type connector
pair(pin header + socket), and this worked well for PATA. I'm guessing this
will not work so well with SATA though. What kind of connectors would work
for SATA1/2? I know the differential impedance is 100ohms, and that the
trace length difference must be within 5 mils. I'm guessing I have to get a
high speed connector that has the same impedance and is able to support 3GHz
speeds? Is that all I need to be looking for?
Thanks.
