Description The HSDL-3209, a low-cost and ultra-small
form factor infrared transceiver, 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 fully compliant to IrDA 1.4 low power
specification from 9.6 kb/s to 115.2 kb/s, and supports HP-
SIR and TV Remotes modes. The design of the HSDL-3209
also includes the following unique features:
- Low passive component count.
- Shutdown mode for low power consumption require-
Selection of Resistor R1
to provide the appropriate peak pulse LED current over
different ranges of Vcc as shown on page 2 under “Recom-
mended Application Circuit Components”.

Interface to Recommended I/O chips The HSDL-3209’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.
Figure 10 shows how the IrDA port fits into a mobile
phone and PDA platform.
The link distance testing was done using typical HSDL-
3209 units with SMC’s FDC37C669 and FDC37N769 Super
I/O controllers. An IrDA link distance of up to 50 cm was
demonstrated.
