Analog Front End Integrated Circuit for 13.
56MHz RFID Base Station
EM4094
General Description
The EM4094 is an analogue front end for 13.
56MHz RFID reader systems.
It is highly versatile so it can be used in different reader systems having sub carrier frequencies from 212kHz to 848kHz, hence covering ISO14443 and ISO15693 standards.
The adaptability is achieved using a 3 wire serial interface to program the system option bits.
The EM4094 operating
voltage is comprised between 3.
3V and 5V.
The push-pull transmitter generates 200mW output RF power into a 50 load.
The output stage drivers are capable of OOK or ASK modulation from 7% up to 30% of AM modulation.
