Tiny IR transceiver puts handsets in home control

27 August 2003 Opto-Electronics

A novel, low-power, infrared transceiver and application software combination can allow cellphones and PDAs to function as universal IR remote control devices for televisions, VCRs, DVDs and other home appliances.

The solution from Agilent Technologies is claimed to be easier to integrate into new product designs and requires fewer external components than competing solutions, and it offers an extended remote control distance of up to 8 m.

The new Agilent HSDL-3003 dual-function transceiver supports both low-power serial infrared (SIR) and remote control operation. The transceiver is compliant with IrDA physical layer Version 1.4 low-power standards and operates at SIR data-rates from 9,6 to 115,2 Kbps.

Offered in a small-profile surface-mount package, with dimensions of 2,7 x 8 x 3 mm, it combines an IrDA link distance of up to 0,5 m. 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 distance. The HSDL-3003 also has a flexible programming mode to enable easy software programming. With a very low idle current (typically 50 µA) and 10 nA shutdown current battery life in mobile devices is extended. In shutdown mode, the PIN diode is inactive, thus generating very little photocurrent even under very bright ambient light.

Agilent's 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 and each device can have up to 32 buttons/functions that can either be controlled via the mobile phones or PDA's touch screen or keypad buttons.
