Hello, As a part of a project I am looking for a FPGA on PCI that has 8 LVDS channels and the driver of this card that enables all the 8 channels of read and write. Total data transfer capacity is 200-400 Mbps. Questions are: 1.Is this data rate achievable? 2.Can anyone point a solution for this design? Any help will be appreciated, Thanks in advance, Marc.
LVDS PCI card is needed

I'm using a PMC module from Transtech DSP that comes with an LVDS buffer module. Not cheap but I am using up to 50 LVDS lines as input/output so I figured it was better to use a known good buffering/ connector solution. The FPGA01, 2, and 3 are pretty good solutions if not exactly cheap.

We can offer a hardware solution to this in our Broaddown2 product. We can support up 17 input lvds pairs and a lot more outgoing. The receive terminator resistors are an option on the board which can be fitted at the cost of 30 pounds UK, or equivalent. You can fit yourself if you are very good with a soldering iron but beware as the resistor sites are 0201 size. The software side would be a custom design with associate costs and timescales. 200-400 Mbit/s is achieveable although at 400 MBit/s you will need some care to get that through-put on the 32bit/33MHz PCI bus.

I presume components this size remove all the headache of decoupling/ terminating BGA designs, but are they easy to get hold of, and where do you source them in the UK (they're not in the RS catalogue :-( ).

Hi, http://www.enterpoint.co.uk/moelbryn/broaddown2.html this board looks nice, also the price is okay... regards, Benjamin

0201 fits nicely on the 1mm via grid underneath the FPGA allowing the optimal termination point. 0201 are not generally available in the common used UK catalogues as yet. Digi-Key do have stock though if you can suffer the US export questions. John Adair Enterpoint Ltd. - Home of Broaddown2.

Austin, hello Thank you for your reply. I have visited the site you mentioned but failed to find an LVDS card with a pci interface. I have noticed that you are a Xlinx member, could you point other companies that implement LVDS on your FPGAS? Thanks in advance, and sorry to bother you, Marc.

soos, Was it: http://www.dyneng.com/pci_lvds.html or, another one of the 907 hits on google for: LVDS Xilinx PCI card I was just using google to find the card. A lot of links to wade through.
