DDC264EVM, analog breadboarding

Other Parts Discussed in Thread: DDC264EVM, DDC232

Thanks to Adam, Praveen, and Eduardo for answering my many questions about the DDC product family and evaluation board.  I now have a working eval board, and I'm ready to proceed to the next step.

Our ultimate intention is to connect a custom 32-element photodiode array device of our own design to a DDC232.  As a first step, we want to replace the DDC264EVM analog daughter board with a breadboard which includes our component.  It will cost far too much for us to make a proper PCB at this stage.

The DDC264EVM receives analog signals from the daughter board through a high-density interconnect socket, the Amphenol FCi 84501-101LF.  We want to build a prototype board with that interconnect.  Unfortunately, the 300-ball grid array which attaches the interconnect to the PCB would be impossible to solder by hand.

I have already requested information from Amphenol FCi, but I thought that I would also try to ask here.  Does a compatible socket with pins exist?  Alternately, is an adapter available?  These would be very helpful to us.  We would prefer to keep the 1.27 mm centers of the existing BGA, but we can also work with 2.54 mm. It doesn't matter to us whether the interconnect is made by Amphenol FCi, as long as it is compatible.
Thanks for any leads.

    John,

    Unfortunately I have only used this connector as part of our EVM PCB and don't know of a socket or adapter. One thing we have done in the past here is to remove the resistors from the Analog Input Board and solder in other connections. With the User's Guide schematic you should be able to do the same. Please let me know if you reach FCI or if you need more information.

    Regards,
