Infrared Encoder/Decoder 14-Pin SOIC N T/R

The device is a low-cost, high-performance, fully-static infrared encoder/decoder. This device sits between a UART and an infrared (IR) optical transceiver. The data received from a standard UART is encoded (modulated), and output as electrical pulses to the IR Transceiver. The IR Transceiver also receives data which it outputs as electrical pulses. The MCP2120 decodes (demodulates) these electrical pulses and then the data is transmitted by the MCP2120 UART. This modulation and demodulation method is performed in accordance with the IrDA standard. Typically a microcontroller interfaces to the IR encoder/ decoder. Infrared communication is a wireless two-way data connection using infrared light generated by low-cost transceiver signaling technology. This provides reliable communication between two devices.
