• Manufacturer Part Number: hsdl-3007
• Description: Irda Data Compliant Low Power 115.2kbit/s With Remote Control Infrared Transceiver
• Manufacturer: ETC-unknow

Description
The HSDL-3007, a wide-
voltage operating range
infrared transceiver, is a low-
cost and ultra small form
factor device that is designed
to address the mobile
computing market such as
PDAs, as well as small
embedded mobile products
such as digital cameras and
cellular phones. It is spectrally
suited to universal remote
control transmission function.
It is fully compliant to IrDA
1.4 low power specification
from 9.6kb/s to 115.2kb/s, and
support most remote control
codes. The design of HSDL-
3007 also includes the
following unique features:
• Spectrally suited to
• Low passive component
• Shutdown mode for low
• Direct interface with I/O

Selection of Resistor R1
Resistor R1 should be selected
to provide the appropriate
peak pulse LED current at
different ranges of Vcc as
shown on page 3 under
“Recommended Application
circuit components”.
Interface to the Recommended I/O
chip
The HSDL3007’s TXD data
input is buffered to allow for
CMOS drive levels. No peaking
circuit or capacitor is required.
Data rate from 9.6kb/s up to
115.2kb/s is available at RXD
pin. The TXD_RC, pin6, is
used to select the remote
control transmit mode.
Alternatively, the TXD_IR,
pin3, is used for infrared
transmit selection.
Figures 5 and 6 show how
HSDL-3007 fits into a mobile
phone and PDA platform
respectively.

Controller
The link distance testing was
done using typical HSDL-3007
units with SMC’s FDC37C669
and FDC37N769 Super I/O
controllers. An IR link distance
of up to 50 cm was
demonstrated.
Remote Control Operation
The HSDL-3007 is spectrally
suited to universal remote
control transmission function.
Remote control applications
are not governed by any
standards, owing to which
there are numerous remote
codes in market. Each of those
standards results in receiver
modules with different
sensitivities, depending on the
carries frequencies and
responsively to the incident
light wavelength.
Agilent’s HSDL-3007 can
acheive a typical RC link
distance of 7m to 8m.
