SIR (Serial Infrared) supports speeds up to 115.2 kbps, while FIR (Fast Infrared) supports up to 4 Mbps. Choose based on your throughput requirements.
IrDA Transceiver Modules Component Intelligence
Selecting and integrating infrared data association modules for legacy and specialized short-range wireless links.
What are IrDA Transceiver Modules components?
IrDA transceiver modules enable short-range, point-to-point wireless data transfer via infrared. When selecting, prioritize data rate (SIR/MIR/FIR), supply voltage, and optical link distance to ensure compatibility with your existing hardware interface.
How to Choose IrDA Transceiver Modules Components
Focus on the physical link requirements and the specific IrDA standard version supported by your host controller.
Data Rate Standards
Match the module to your protocol requirements: SIR (up to 115.2 kbps), MIR (1.152 Mbps), or FIR (4 Mbps).
Supply Voltage
Verify the module's operating voltage (typically 2.7V to 5V) against your system's power rail to avoid level shifting.
Optical Link Distance
Ensure the transceiver's intensity and receiver sensitivity meet your required physical separation distance.
Package Footprint
IrDA modules are often legacy parts; verify the physical package and pinout against your PCB layout.
Shutdown Current
For battery-powered designs, check the shutdown or standby current to minimize power consumption when idle.
