Agilent Technologies have introduced the industry's fastest low-power infrared (IR) transceivers that offer IrDA (Infrared Data Association)-compliant data transmission at up to 4Mb/s and enable mobile phones and PDAs to function as universal IR remote controls for televisions, VCRs, DVDs and other home appliances.
A 4Mb/s data rate means that Agilent>'s HSDL-3020 and HSDL- 3021 transceivers can transfer a 640 x 480-pixel photo in approximately 0.7s, and a 329MB 1280 x 960-pixel image in approximately 2.3s. Such speeds are becoming critical as the newest camera- phone designs now permit applications such as downloading pictures directly to photo-quality printers.
The HSDL-3021 transceiver provides a remote control distance of up to 8m (approximately 26ft) and the HSDL- 3020 up to 14m (approximately 46ft). Both transceivers provide an IrDA link distance of up to 50cm (approximately 20in.) from 9.6 to 4.0Mb/s, and compatibility with Agilent's universal remote control software. Both also feature a separate 875nm-wavelength infrared LED for IrDA data transmission and 940nm LED for IR remote control; however, the HSDL- 3020 comes with an enhanced three- lens optical package for optimised IrDA and remote control performance. Package dimensions for the HSDL- 3020 are 2.5mm high x 10.4mm wide x 2.95mm long. Dimensions for the HSDL-3021 are 2:5mm x 8mm x 3mm:
Both units feature low power operation, with a logic input/output interface operating at only 1.8V, shutdown currents of only 10μA, and standby current of 0.1mA. The transceivers can be used for IrDA and remote control applications without additional external components for multiplexing. The HSDL-3020 and HSDL-3021 are fully compliant with IrDA Physical Layer specification version 1.4 low power from 9.6kb/s to 4.0Mb/s (FIR). Both versions provide LED stuck-high protection and are capable of operating with power sources ranging from 2.4V to 3.6V. All Agilent IR transceivers are IEC 825-Class 1 Eye Safety compliant.
The Agilent HSDL-3020 and the HSDL-3021 are available now through Agilent's direct sales channel and worldwide distribution partners.
