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 50Ω load and is capable of
OOK or ASK modulation.
