IrDA^ Data Compliant Low Power
115.2 kbit/s Infrared Transceiver
Data Sheet
Description
Features
The HSDL-3209 is an ultra-small low cost infrared trans-
ceiver module that provides the interface between logic
and infrared (IR) signals for through air, serial, half-duplex
IR data link. It is designed to interface to input/output
logic circuits as low as 1.5V. The module is compliant to
IrDA Physical Layer Specifications version 1.4 Low Power
from 9.6 kbit/s to 115.2 kbit/s with extended link distance
and it is IEC 825-Class 1 eye safe.
The HSDL-3209 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.
