I saw on AD9048 product page that this chip is obsolete. ADI suggested to use AD9057, but it is not for pin to pin. I would like to verify from ADI side that if there is really no pin-to-pin replacement for AD9048?
As I recall, there were multiple vendors selling ADCs in this pinout in the 1990s. ADI obsoleted this product many years ago, and does not have a pin for pin replacement. I'm not aware of any other vendor still offering this pinout, but I cannot tell you definitively that they don't exist. It's also possible that our authorized reseller for discontinued products, Rochester Electronics , may have stock on these parts (unlikely, but worth a try). http://www.rocelec.com/
