HSDL-3020
IrDA^® Data Compliant Low Power 4.0 Mbit/s
with Remote Control Infrared Transceiver
Data Sheet
Description
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)andIEC825Class1eyesafetystandards.
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.
