Description
The HSDL-3200 is a new
generation of low-cost Infrared
(IR) transceiver module from
Agilent Technologies. It features
the smallest footprint in the
industry at 2.5 H x 8.0 W x 3.0 D
mm. The supply voltage can
range from 2.7 V to 3.6 V. The
LED drive current of 25 mA
assures that link distances meet
the IrDA Data 1.2 (low power)
physical layer specification.
The HSDL-3200 meets the link
distance of 20 cm to other low
power devices, and 30 cm to
standard 1 meter IrDA devices.

Note
Note:
4. C1 must be placed within 0.7 cm of the HSDL-3200 to obtain optimum noise
immunity.
Caution: The BiCMOS inherent to this design of this component increases the component’s
susceptibility to damage from electrostatic discharge (ESD). It is advised that normal static
precautions be taken in handling and assembly of this component to prevent damage and/or
degradation which may be induced by ESD.

Note:
5. An in-band optical signal is a pulse/sequence where the peak wavelength,
λp,
is defined as 850 nm
≤ λp ≤
900 nm, and the pulse
characteristics are compliant with the IrDA Serial Infrared Physical Layer Link Specification.
