The EM4095 (previously named P4095) chip is a CMOS integrated transceiver circuit intended for use in an RFID basestation to perform the following functions:
- antenna driving with carrier frequency
- AM modulation of the field for writable transponder
- AM demodulation of the antenna signal modulation induced by the transponder
communicate with a microprocessor via simple interface.
Features
Integrated PLL system to achieve self adaptive carrier frequency to antenna resonant frequency
No external quartz required
100 to 150 kHz carrier frequency range
Direct antenna driving using bridge drivers
Data transmission by OOK (100% Amplitude Modulation) using bridge driver
Data transmission by Amplitude Modulation with externally adjustable modulation index using single ended driver
