IC/Module: MCP2120 Infrared Encoder/Decoder
MCP2120 is a fully-static infrared encoder/decoder that sits between the UART side and an infrared (IR) optical transceiver. A standard UART encodes the data received and output as electrical pulses to the IR Transceiver. This data is received by the IR Transceiver which it outputs as electrical pulses. The electrical pulses are decoded by the MCP2120 and then the data is transmitted via the MCP2120 UART. This modulation and demodulation method is performed in accordance with the IrDA standard.
IC/Module: TFDU4101 Infrared Transceiver Module
The TFDU4101 is an infrared transceiver module that supports IrDA speeds up to 115.2 kbit/s, and carrier based remote control modes. This module comprises of a photo pin diode, an infrared emitter (IRED), and a low-power control IC to provide a total front-end solution. It has a tri-state-receiver output and is floating in shutdown mode with a weak pull-up.
