Agilent Technologies Inc. introduced the industry's smallest, lowest-power infrared (IR) transceiver that enables mobile phones and PDAs to function as universal IR remote controls for televisions, VCRs, DVDs and other home appliances.

The new transceiver offers a remote control distance of up to 7m (approximately 23 feet) with an IrDA (infrared data association) link distance of up to 50cm and compatibility with the company's universal remote control software.

Agilent reports that the device is supplied in the industry's smallest package, measuring 1.6(H)-by-7(W)-by-2.8(L)mm. They also lay claim to the industry's lowest power operation, with a logic input/output interface operating at 1.8Vdc. The transceiver can be used for IrDA and remote control applications without additional external components for multiplexing.

Compliant with IrDA Physical Layer version 1.4 low-power standards, the transceiver operates at SIR (serial infrared) data rates from 9.6kbps to 115.2kbps. It features a typical idle current of

The transceiver has a flexible programming mode to enable easy software programming. 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 (eight profiles x ten devices). Each device can have up to 32 buttons/functions, which can be controlled via the mobile phone or PDA touch screen or keypad buttons.

The Agilent HSDL-3007 is available now and is priced at $1.50 each in moderate volumes.
