... 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 performed in accordance with the IrDA standard ...
