Transceiver

Description

The HSDL-3003, a wide-voltage

operating range infrared

transceiver is a low-cost and 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 at 940 nm

typically. It is fully compliant to

IrDA 1.4 low power specification

from 9.6 kb/s to 115.2 kb/s, and

supports most remote control

codes. The design of the HSDL-

3003 also includes the following

unique features:

• Spectrally suited to universal

remote control transmission

function at 940 nm typically.

• 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 Vcc as shown on page 3

under "Recommended Application

Circuit Components".

Interface to Recommended I/O Chips

The HSDL-3003’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

TXD_RC, (pin 7), or the

TXD_IrDA, (pin 3), can be used

to send remote control codes.

The block diagrams below show

how the IrDA port fits into a

mobile phone and PDA platform.
