Agilent HSDL-3209
IrDA
Data Compliant Low Power
115.2 kbit/s Infrared Transceiver
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.
