Appendix D: General Application
Guide for the HSDL-3603 Infrared
IrDA
Compliant 4 Mb/s Transceiver
Description
The HSDL-3603 wide voltage
operating range infrared trans-
ceiver is a low-cost and small
form factor that is designed to
address the mobile computing
market such as notebooks, print-
ers, and LAN access as well as
small embedded mobile products
such as digital cameras, cellular
phones, and PDAs. It is fully com-
pliant to IrDA 1.4 specification
up to 4 Mb/s. The design of the
HSDL-3603 also includes the
following unique features:
Low passive component count.
Shutdown mode for low power
consumption requirement.
Single-receive output for all
data rates.
Selection of Resistor R1
Resistor R1 should be selected to
provide the appropriate peak
pulse LED current over different
ranges of V
CC
. The recommended
selection of R1 is tabulated in the
table on page 3. The HSDL-3603
typically provides 180 mW/Sr of
intensity at the recommended
minimum peak pulse LED current
of 400 mA.
Interface to Recommended I/O chips
The HSDL-3603’s TXD data input
is buffered to allow for CMOS
drive levels. No peaking circuit or
capacitor is required.
Data rate from 9.6 kb/s up to 4
Mb/s is available at the RXD pin.
Following shows the interface of
HSDL-3603 with National
Semiconductor’s Super I/Os, and
the SMC I/O chips.
