The HSDL-3003 is a small form factor enhanced infrared (IR) transceiver module that provides the capability of (1) interface between logic and IR signals for through-air, serial, half-duplex IR data link, and (2) IR remote control transmission operating at the optimum 940 nm wavelength for universal remote control applications. For IR data communication, the HSDL-3003 provides the flexibility of low power SIR applications and remote control applications with no external components needed for the selection of the type of application. The transceiver is compliant to IrDA Physical Layer Specification Version 1.4 Low Power from 9.6 kbit/s to 115.2 kbit/s (SIR) and it is IEC 825-Class 1 Eye Safe. The HSDL-3003 has very low idle current and can be shutdown completely to achieve very low power consumption. In the shutdown mode, the PIN diode will be inactive and thus producing very little photocurrent even under very bright ambient light. Such features are ideal for battery operated handheld products such as PDAs and mobile phones.
