The resistor value chosen above
is for optimal IrDA operation. For
optimized remote control
performance, it is recommended
to turn on both the 870 nm and
940 nm LEDs. Moreover,
separate power control feature
can be incorporated for remote
control operation by implement-
ing device as shown in Figure 3.
computing market such as PDAs,
as well as small embedded mobile
products such as digital cameras
and cellular phones. It also
includes a 940 nm LED to
support universal remote control
applications. It is fully compliant
to IrDA 1.4 low power specifica-
tion from 9.6 kb/s to 115.2 kb/s,
and supports most remote control
codes. The design of the HSDL-
3002 also includes the following
unique features:
An additional spectrally suited
940 nm LED
Low passive component count.
Shutdown mode for low power
consumption requirement.
Selection of Resistor R1
Resistor R1 should be selected to
provide the appropriate peak
pulse LED current over different
ranges of V
CC
as shown in the
table below.
Interface to Recommended I/OChips
The HSDL-3002’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 115.2 kb/s is
available at the RXD pin. The
V(RC), pin 2, in conjunction with
TxD (IrDA), pin 3, can be used to
send remote control codes. Pin 2
is driven through a switching FET
transistor with a very low on-
resistance capable of driving 400
mA of current for remote control
operation.
The block diagram below shows
how the IrDA port fits into a
mobile phone and PDA platform.
