Once the contacts in the case of a BGA become inaccessable to direct probing at the part, which is sometimes necessary to determine an open circuit condition, or even a short, the Joint Test Action Group got together and thought it would be nice if the designer still had access to as many nodes...
mukund,
I am quite certain that given a choice most folks would choose to obtain a sigma-delta type converter if it could match the sample rates of the pipelined types. However, I don't believe that this will happen any time soon. The reason that I don't think this will happen is that the...
Steve, regardless of the data you may find in standard references and web sites, you may find as I have found several times now that the best pad size dimensions will come from the contract manufacturer that places and flows the board for you (they may actually be different). They will be able...
Hello mukund,I have been using high speed ADCs for the past 2 years now (~100MSPS) and would be glad to discuss any issues. I am also somewhat curious about attempting to design the 100MEG sigma-delta converter that Nasir mentioned. I haven't seen any sigma-delta type product ever go faster...
