EM4097 Overview
The EM4097 (previously named P4097) chip is a CMOS integrated transceiver circuit intended for use in an RFID basestation to perform the following functions: Antenna driving with carrier frequency to transfer energy to the transponder Data transfer to writable transponder by amplitude modulation (ASK) of the field (100% modulation ratio, called OOK, “on”-“off” keying) Data transfer from transponder by amplitude- or...
