Transceivers combine fast data with
control
Two new low-power infra-red transceivers ffer IrDA-compliant data transmission at up to 4Mbit/s and enable mobile phones and PDAs to function as universal IR remote controls.
Agilent Technologies today introduced the industry's fastest low-power infra-red (IR) transceivers that offer IrDA-compliant data transmission at up to 4Mbit/s and enable mobile phones and PDAs to function as universal IR remote controls for televisions, VCRs, DVDs and other home appliances A 4Mbit/s datarate means that Agilent's HSDL-3020 and HSDL-3021 transceivers can transfer a 640 x 480-pixel photo in approximately 0.7s and a 329Mbyte 1280 x 960-pixel image in approximately 2.3s

Hot-pluggable transceiver for Fibre Channel
Agilent Technologies has announced volume availability of its 2Gbit/s small-form-pluggable (SFP) fibre-optic transceiver for Fibre Channel storage area networks (SANs).
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 and the HSDL-3020 up to 14m.
Both transceivers provide an IrDA link distance of up to 500mm from 9.6Kbit/s to 4.0Mbit/s, and compatibility with Agilent's universal remote control software.
Both also feature a separate 875nm-wavelength infra-red 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 2.5 x 10.4 x 2.95mm.
Dimensions for the HSDL-3021 are 2.5 x 8 x 3mm.
Both units feature low power operation, with a logic input/output interface operating at only 1.8V, shutdown currents of only 10uA, 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 9.6Kbit/s to 4.0Mbit/s (FIR).
Both versions provide LED stuck-high protection and are capable of operating with power sources ranging from 2.4 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. Request a free brochure from Avago Technologies ...
