Analog Front End Integrated Circuit for
13.56MHz RFID Base Station
General Description
The EM4094 is an integrated analog system for
13.56MHz RFID reader system. It is highly versatile so it
can be used in different reader systems having
sub-carrier frequencies from 212KHz to 848KHz, hence
covering ISO 14443 and ISO 15693 standards.
The adaptability is achieved using a 3 wires serial
interface to program the system option bits.
The transmitter generates 200 mW output power into
50
load and is capable of OOK or ASK modulation.
Applications
Low cost reader solution
Hand held reader
