Description:
Infrared light, commonly referred to as “IR”, is a common easy-to-use, low power and low-cost media to transmit information. Among the few “wireless” communicatio choices, IR has the significant advantage of compatibility with hundreds of millions of electronic devices with IR ports (i.e., laptop PCs, PDAs). The vast majority of IR-capable devices are compatible with a set of standards established by the Infrared Data Association, or IrDA®. These standards include guidelines for implementing the IR Physical Layer (IrDA Serial Infrared Physical Layer specification), ensuring that IR communication can be established through free space between two dissimilar devices. This document describes the fundamentals of the infrared physical layer, the IrDA standard and selecting the proper discrete emitter and photodiode components for circuit implementation.
