Rfmd-rf2172

Hi, I have a RFID reader having the an RFMD made RF-2172 IC
the problem is that this is no longer in production and there is no pin-to-pin equivalent for the above. can any one hlep in finding the equivallent for it.
PS. I tried contacting the manufacturer of the reader, but there was no reply.

Most places like these **broken link removed** want orders for lots and won't talk to you.
