Description
The HSDL-3201 is one of a new
generation of low-cost Infrared (IR)
transceiver modules from Avago
Technologies. It features 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 drive current is internally
compensated to a constant 32 mA to
assure that link distances meet the
IrDA Data 1.4 (low power) physical
layer specifications.
The HSDL-3201 meets the 20 cm link
distance to other IrDA 1.4 low power
devices, and a 30 cm link distance to
IrDA 1.4 standard devices.

Notes
Connect to system ground.
This pin must be left unconnected.
Regulated: 2.7 to 3.6 Volts
Connect to a “quiet” ground.
This pin must be driven either high or
low. Do NOT float the pin.
Output is a low pulse for 2.4 s
Logic high turns the LED on. If held
high longer than ~ 20 s, the LED is
turned off. TXD must be driven high
or low. Do NOT float the pin.
May be unregulated: 2.7 to 6.0 volts.
Connect to system ground via a low
inductance trace. For best
performance, do not directly connect
to GND or AGND at the part.
