General 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
mo
Key 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/EM4305).
