Agilent 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 Agilent
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.
