The HSDL-3020 is a new generation low profile high speed 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. The HSDL-3020 features an enhanced 3 lens optical package for optimized IrDA and RC performance. The module is fully compliant to IrDA Physical Layer specifi-cation version 1.4 low power from 9.6 kbit/s to 4.0 Mbit/s (FIR) and IEC825 Class 1 eye safety standards. The HSDL-3020 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. It is also designed to interface to input/output logic circuits as low as 1.5 V. These features are ideal for battery operated mobile devices such as PDAs and mobile phones that require low power consumption.
