Transceiver combines IrDA with remote control

Agilent has developed the industry's first infra-red (IR) transceiver to combine IrDA (Infra-red Data Association) compatibility with infra-red remote control operation.

Agilent has developed the industry's first infra-red (IR) transceiver to combine IrDA (Infra-red Data Association) compatibility with infra-red remote control operation.

The release of the Agilent HSDL-3002 allows manufacturers to enable consumers to use handheld PDAs and mobile phones to activate and control, at a distance of up to 6m, consumer appliances such as home entertainment systems, DVD players and almost anything else using an infra-red remote control.

The new IR transceiver also offers an extended IrDA short-range link distance of up to 50cm as opposed to the standard IrDA low power specification of 20 to 30cm.

This allows the PDA or phone to transfer data, such as "point and pay" infra-red financial management (IrFM) transactions, business cards, messages or files, over an increased, more convenient, distance.

"Most of today's PDA designs already have the hardware capability to record and transmit remote control signals", said Kee Hane Ngoh, operations manager of Agilent's Infra-red Products Operation.

"This two-in-one transceiver technology provides manufacturers with a way to substantially increase the value of their products at very little additional cost".

The Agilent HSDL-3002 IR transceiver is offered in an 8-pin, low profile surface mount package, with dimensions of 2.7 x 9.1 x 3.65mm.

It is fully compliant with IrDA Physical Layer 1.4 low-power standards and operates at serial infra-red (SIR) data rates of 9.6 to 115.2Kbit/s.

The IR transceiver's remote control feature operates at a wavelength of 915 to 965nm, providing a link distance up to 6m.

The IR transceiver is specifically designed for low power consumption.

Its shutdown current of just 10nA helps extend battery life in mobile devices.

Even during higher-power remote control operation, the HSDL-3002 IR transceiver is compliant with the IEC 825-Class 1 Eye Safe Standard.

Infra-red radiant intensity can be hazardous to the human eye if it does not fall within specified safe limits, and a warning label is mandated if a product fails to meet the IEC standard.

All Agilent IR transceivers are IEC825 Class 1 compliant.

The HSDL-3002 IR transceiver is immediately available for volume order through Agilent's sales offices worldwide.

The transceiver also is available through Agilent's distribution partners.
