Chris.

That's real nice. I used to use Gennum in products we did years ago for digital 
video interface and designs. They have been making these part types for about 
15 years now. 

I guess this is a stroke of good luck. When I read your message I thought, ah 
what the heck lets just throw that one out there and see what happens and it 
worked.

Richard,



Thanks for the info.  That's exactly the type of chip that I was
looking for.  It didn't show up in my searches.

Have you talked to Gennum? http://www.gennum.com. See Datacom products. 

Example: 4 channel Serdes, each channel up  to 5Gb/s. Part number GN1405C.

I've been looking at ways to implement 16 5Gbps SERDES channels and it 
seems that to get this speed you need to use one of the really expensive 
FPGAs (i.e. much greater than $1K per chip).  I don't need a ton of 
non-SERDES logic, so I'm looking for a more reasonably priced solution.  
I'm even amenable to non-FPGA implementations.  Any thoughts?

Thanks,

Chris
