EM4097 Product details

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 communica

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).
