Agilent HSDL-3603 IrDA® Data Compliant 4 Mbit/s Infrared Transceiver
Data Sheet
Features · Fully compliant to IrDA 1.4 Fast Infrared (FIR) from 9.6 kbit/s to 4 Mbit/s · Typical link distance > 1.5 m Description The HSDL-3603 is a low profile infrared transceiver module that provides interface between logic and IR signals for through-air, serial, half-duplex IR data-link. The module is fully compliant to IrDA Date Physical Layer Specifications v1.4 Fct Infrared (FIR) and IEC825Class I Eye Safe. The HSDL-3603 can be shut down 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 mobile devices that require low power consumption. Applications · Digital imaging Digital still cameras Photo-imaging printers · Data communication Notebook computers Desktop PCs WinCE handheld products Personal Digital Assistants Printers Auto PCs Dongles Set-top box · Digital imaging Digital cameras Photo-imaging printers · Telecommunication products Mobile phones Pagers · Electronic wallet · Small industrial and medical instrumentation General data collection devices Patient and pharmaceutical data collection devices · IR LANs · Miniature package Height: 3.90 mm Width: 9.80 mm Depth: 4.65 mm · Guaranteed temperature performance, -25 to 70°C Critical parameters are guaranteed over temperature and supply voltage · Low power consumption Low shutdown current (10 nA typical) Complete shutdown of TXD, RXD, and PIN diode · Withstands >100 mVp-p power supply ripple typically · VCC supply 2.7 to 5.25 volts · Integrated EMI shield · LED stuck-high protection · Designed to accommodate light loss with cosmetic windows · IEC 825-Class 1 eye safe · Interface to various super I/O and controller devices

I/O Pins Configuration Table Pin 1 2 3 Symbol LED A LED C TXD Description LED Anode LED Cathode Transmit Data I/O Type Input Output Input, Active High Output, Active Low Function This pin can be connected directly to VCC (i.e., without series resistor) at less than 3 V. Please refer to Table 1 for VCC versus Series Resistor, R1. Leave this pin unconnected. This pin is used to transmit serial data when SD/Mode pin is low. If this pin is held high longer than ~100 µs, the LED would be turned off when used in conjunction with the SD/Mode pin. TXD is low at initialization. This pin is capable of driving a standard CMOS or TTL load. No external pull-up or pull-down resistor is required. It is in tri-state mode when the transceiver is in shutdown mode and during digital serial programming operations. RXD is high at initialization. The transceiver is in shutdown mode if this pin is high for more than 400 µs. On the falling edge of this signal, the state of the TXD pin sampled and used to set receiver low bandwidth (TXD=low) or high bandwidth (TXD=high) mode. See Figure 2 for bandwidth selection timings. SD is low at initialization. Regulated, 2.7 to 5.25 Volts.

Notes

Notes: 1. CX1 must be placed within 0.7 cm of the HSDL-3603 to obtain optimum noise immunity. 2. In environments with noisy power supplies, supply rejection performance can be enhanced by including CX2, as shown in Figure 1: "HSDL-3603 Functional Block Diagram" on Page 2.
