Many believe that mobile phones will eventually include more complex and more high-tech functions. With Agilent Technologies Inc.'s infrared (IR) transceiver, mobile phones will now be able to function as universal IR remote control devices for televisions, VCRs, DVDs, and other home appliances.

The compact, low-cost HSDL-3005 transceiver offers a remote control distance of up to 7m or approx. 23ft with an IrDA (Infrared Data Association) link distance of up to 50cm. It achieves its low cost and compact size through the use of a single, high-power 883nm wavelength LED for IrDA and remote control operation, rather than providing a separate 875nm emitter for IrDA and 940nm emitter for remote control.

The transceiver is available in two versions - front view and side view. In the front view version, the optics that are on top of the package are for IR transmission/reception via the front or back of a handheld device. In the side view version, the optics, which are located at the side of the package, are for IR transmission/reception via the edge of a handheld device. The front view package measures 8(W)-by-2.5(H)-by-3(L)mm, while the side-view version has a measurement of 7.50-by-2.80-by- 3.35mm.

The HSDL-3005 has a flexible programming mode to enable easy software programming. According to the company, the complementary HSDL-S300 application software is a universal remote control program with a predefined remote control database and a self-teach/learn mode.

The software incorporates profiles for TV, DVD, VCR, air conditioning, CD, audio, LD/VCD (laser disk/video compact disk) and other home appliances. Each profile can have up to 10 sets of device controls, thus 80 home appliance devices can be stored.

The HSDL-3005 transceiver is compliant with IrDA Physical Layer v1.4 low-power standards and operates at SIR data rates from 9.6Kbps to 115.2Kbps. Its combination of low idle current of <100mA and shutdown current of 10nA helps extend battery life in mobile devices. The device also provides LED stuck-high protection and is capable of operating with power sources ranging from 2.4V to 3.6V.

In moderate volumes, the HSDL-3005 is priced at less than $1.50.
