Microchip MCP2120-I/SL

红外线编码器/解码器2.5V ~ 5.5V2.5V ~ 5.5V表面贴装型

Overview

The MCP2120-I/SL is a low-cost high-performance fully-static Infrared Encoder/Decoder sits between an 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 that the MCP2120-I/SL decodes (demodulates) then transmits the data via the MCP2120-I/SL 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 transceiver signalling technology. This provides reliable communication between two devices.
