2 KHZ RFID BASESTATION APPLICATIONS Description 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 phase demodulation (ASK or PSK)  µC Interface to communicate with a microprocessor Features  Integrated PLL system to achieve self adaptive carrier frequency to antenna resonant frequency  Chip can be forced to run with external clock, division ratio 32  100kHz to 150kHz carrier frequency range Read/Write Mode using internal PLL signal  Direct antenna driving using bridge driver  Data transmission...
