HSDL-3021

The HSDL-3021 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, halfduplex IR data link, and (2) IR remote control transmission for universal remote control applications. The HSDL-3021 can be used for IrDA as well as remote control application without the need of any additional external components for multiplexing.

The HSDL-3021 is fully compliant to IrDA® Physical Layer specification 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-3021 can be shut down completely to achieve very low power consumption. In the shutdown mode, the PIN diode will be inactive and thus produce 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.
