Can you send me more detailed specs ? e.g. is it 10Mb/s per channel or together ? Is the burst size limited ? What is the max. required recording speed in Mbyte/s ?

What is the max. file size ?

1.25 Mbytes/sec. continuous speed seems to be too high !
Do you need it for one test only or is it for production?
Is the cost critical ?

Are the four data streams independent or do they have to
be recorded preserving the timing info ?

The speed is 10mbits/sec per channel - no mention is made as to whether it's continous or burst - I believe it's continous. The TAXIchips (now CYPRESS Hotlink chips will do that speed easy). We have decided to build our own card using FPGA and HOTLINK. Each channel needs to be recorded separately and timing needs to be preserved.

Thanks for your response.

The HOTLINK does the S/P conversion. You have to put this info into a FIFO, add the timing info (FPGA ?).

The PC has to read this out and write it to the disk and
this is where the overhead comes in. I don't think you can
record it at 5 Mbyte/s (neglecting the timing info)at least not continuously.

You may have to use multiple PC-s and you must know the max. amount of data in advance.
