HSDL-3210
IrDA® Compliant Low Power
1.15 Mbit/s Infrared Transceiver
Data Sheet
Description
The HSDL-3210 is one of a new generation of low-cost
Infrared (IR) transceiver modules from Avago
Technologies. It features one of the smallest footprint
in the industry at 2.5 H x 8.0 W x 3.0 D mm. Although
the supply voltage can range from 2.7 V to 3.6 V, the
LED is driven by an internal constant current source of
60 mA at SIR data rates and 150 mA at MIR data rates.
The HSDL-3210 incorporates the capability for
adjustable optical power. The optical power can be
adjusted lower when the nominal desired link distance
is very short. At 5 cm link distance, only 6% of the full
power is required.
The HSDL-3210 supports the Serial Interface for
Transceiver Control Specification that provides a
common interface between the transceiver and
controller. It is also designed to interface to input/
output logic circuits as low as 1.5 V.
