CRX14 I2C Short Range Contactless Coupler

The CRX14 is a contactless coupler, compliant with the short range ISO14443B standard controlled, using the two wire I²C bus. The CRX14 generates a 13.56MHz signal on an external antenna. Transmitted data are modulated using Amplitude Shift Keying (ASK) modulation. Received data are demodulated from.
