IrDA^® Data Compliant Low Power 4.0 Mbit/s
Infrared Transceiver
Data Sheet
Description
The HSDL-3220 is a new ­ generation low profile high
speed infrared transceiver module that provides inter-
face between logic and IR signals for through-air, serial,
half-duplex IR data-link. The module is fully compliant
to IrDA Physical Layer specification version 1.4 low
power from 9.6kbit/s to 4.0 Mbit/s (FIR) and is IEC825-
Class 1 Eye Safe.
The HSDL-3220 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 1.8V. These features are ideal for
mobile devices that require low power consumption.
