hi all,
Can someone tell me what is the use of the aux_sync_out ?This is the
aux_sync_out cable from J11 on the Roach2.The J10 is for the aux_sync_in,all
this from the all roach2s can be put into a sync singal like 1pps.But what is
the J11 use for?
Best regards!

Hi all.
After looking further into this, I think for our purposes the MSX1024 is
the way to go. It has 48 10 gbe ports with SFP+ that we can use with
optical transcievers. I don't think there's a 4-1 splitter cable with the
ability to use optical SFP+ transcievers, so we'll have to limit our
Or does someone know of a 40-10 optical cable?
Yes, and mellanox have them, including the fibre cable itself in short
distances. But it's only multi-mode (40GBASE-SR4 to 4x 10GBASE-SR) so
you're limited to ~100m or so. It uses an MTP connector on the 40G side,
and an LC connector on the 10G
Just be careful with the 1036 and breaking the 40g ports out to 10g. you can't
break out all the ports, and when you break one out, you sometimes lose another
40g port!

John - Mellanox hides this information in the back of their manuals in my
experience. Best to download.

I know of some applications that only need relatively crude time
alignment that use this port, J11, to daisy chain their start signal
from 1 Roach2 to a second Roach2.

I just noticed that! It's true also with the 1024.

Hi
Jack observed my design and he made some suggestions (thanks for your
help). One is simulate each of the blocks of my design. He told me some
suggestions to simulate, however I would like to know if someone has some
simulation models for PFB, FFT, EQ and DIRX.
I learn more observing :-)
