[casper] Question about the use of aux_sync_out interface(J11)

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! peter

Re: [casper] Network Switches

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

Re: [casper] Network Switches

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

Re: [casper] Network Switches

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! Jason Manley CBF Manager SKA-SA Cell: +27 82 662 7726 Work: +27 21 506 7300 On 03 Sep 2014, at 15:07, John Ford

John - Mellanox hides this information in the back of their manuals in my experience. Best to download. L. On 9/3/14, 9:11 AM, Jason Manley wrote: 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

Re: [casper] Question about the use of aux_sync_out interface(J11)

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. 1PPS source - J10 on Roach2-A - Roach2-A FPGA - J11 on Roach2-A - J10 on Roach2-B If memory serves the latency was a 20 to

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! I just noticed that! It's true also with the 1024. Jason Manley CBF Manager SKA-SA Cell: +27 82 662 7726 Work: +27

[casper] test simulink blocks

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 :-) Best
