1 / 16 page  HSDL-3209 IrDA Data Compliant Low Power 115.2 kbit/s Infrared Transceiver Data Sheet Description The HSDL-3209 is an ultra-small low cost infrared trans- ceiver module that provides the interface between logic and infrared (IR) signals for through air, serial, half-duplex IR data link. It is designed to interface to input/output logic circuits as low as 1.5V. The module is compliant to IrDA Physical Layer Specifications version 1.4 Low Power from 9.6 kbit/s to 115.2 kbit/s with extended link distance and it is IEC 825-Class 1 eye safe. The HSDL-3209 can be shutdown completely to achieve very low power consumption. In the shutdown mode, the PIN diode will be inactive and thus producing very little photocurrent even under very bright ambient light. Such features are ideal for battery operated handheld products. Features • Fully Compliant to IrDA 1.4 Low Power Specification from 9.6 kbit/s to 115.2 kbit/s • Miniature Package - Height : 1.60 mm - Width : 7.00 mm - Depth : 2.80 mm • Guaranteed Temperature Performance, -25 to +70 °C - Critical parameters are guaranteed over tempera- ture & supply voltage • Low Power Consumption - Complete shutdown of TXD, RXD, and PIN diode • Vcc Supply 2.4 to 3.6 Volts • Interface to Input/Output Logic Circuits as Low as 1.5V • LED Stuck-High Protection • Designed to Accommodate Light Loss with Cosmetic Windows • IEC 825-Class 1 Eye Safe • Lead-free and RoHS Compliant Applications • Mobile Telecom - Mobile Phones - Pagers - Smart Phone • Data Communication - PDAs - Portable Printers • Digital Imaging - Digital Cameras - Photo-Imaging Printers • Electronic Wallet Functional Block Diagram Figure 1.
