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 by OOK (100% Amplitude Modulation) using bridge driver
● Multiple transponder protocol compatibility, (Ex.: EM4102, EM4200, EM4450 and EM4205/E...
