[casper] doubling the system sampling rate with time-interleaved ADC boards

Hi all, I have two 3 Gsps ADC boards. And I want to get 6 Gsps sampling rate by time-interleaving these two ADC boards. After searching the capser website, I found that a 3GHz spectrometer have used two ADC083000 boards to reach 6 Gigasamples/second rate. The link is

) or single-pol inputs? What will the correlator be used for? I'd suggest having a look at Mellanox OFED / libvma first (partly because I'm interested to hear how well it works!), and then the NTOP tool. I've heard hashpipe is quite easy to get started with also. - Danny shu.lean wrote: Hi Danny

Re: [casper] specification of computer with NIC and GPU card to do X Engine

. If you're about to build something big, I would highly recommend you purchase some cards from different vendors and do some lab tests. It may turn out that one card in particular has a killer feature. Please let us all know if you do! - Danny shu.lean wrote: Hi all, if using GPU to do X Enigne, what

[casper] some questions about the SFP+ mezzanine card that plugs into roach2

Hi all, Do anyone have experience on configuration of 10Gbe PHY chip? for example,SFP+ mezzanine card that plugs into roach2 is used in two different system. One's transmission distance is more than 300m and the cable is made of fiber. Another's transmission distance is only 3m and the cable

[casper] broadcom BCM8747

Hi all, Do anyone here have any experiences in Broadcom's PHY chip BCM8747? I have a Xilinx Virtex 6 FPGA board and a 10 gigabit ethernet expansion board that has 4 PHY chips (BCM8747). There are ZD connectors between the two boards. And I came across some problems. I am sure that the
