EM4094数据手册RF/IF射频/中频RFID的RFID射频接入监控IC规格书PDF

描述 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 200mW output power into 50 Ohms load and is capable of OOK or ASK modulation.
Solutions
