RPM871-H14E2A Sensors, Transducers

IrDA Transceiver Modules, offer an effective way to replace multi-wire cables with an infrared light-based wireless data transfer protocol. The RPM871-H14E2A is a highly integrated IrDA transceiver module designed to operate at up to 4 Mbps in an IrDA-compliant digital communication system. The RPM871-H14E2A is especially suited for infrared communication between peripheral equipment and smart phones, PDAs, digital cameras, and the like.

The most basic application for RPM871-H14E2A is data transfers between two devices. The module consists of an infrared-emitting diode, infrared receiver, and digital signal transmitter/processor. When an infrared signal is detected, the module provides power to the driver circuit and switches the infrared receiver to receive the signal. The pulse/waveform demodulation is accomplished by the integrated signal processing unit, which converts the IR signals into voltage-level signals for further processing.

The RPM871-H14E2A consists of a parallel interface with up to 14 LEDs allowing multiple devices to be connected at once. This multi-device connection with data rate up to 4 Mbps provides a great advantage of fast transfer rate. The integrated RF shield ensures robust data transfer when using the legacy infrared communication protocol.

In terms of power consumption, the RPM871-H14E2A utilizes a low-power design, allowing it to operate at a wide range of supply voltages. It is designed with low standby current that is suitable for battery-powered applications. The module also supports over-voltage and reverse-polarity protection.

Finally, the RPM871-H14E2A offers an IP67 waterproof protection that makes it suitable for applications in harsh and wet environments. Furthermore, the module has an optional footprint for external antenna. It is designed and tested in order to meet the Bluetooth and FCC requirements for electronic devices.
