Protocol improves infra-red data
throughput
IrSimple protocol software is a new global IrDA standard for camera phones, digital cameras and other mobile devices incorporating IrDA infra-red communications hardware.
Avago Technologies' IrSimple protocol software is a new global IrDA (Infrared Data Association) standard for camera phones, digital cameras and other mobile devices incorporating IrDA infra-red communications hardware Avago's ASDL-S900 IrSimple protocol software can be implemented alone or coexist with existing IrDA protocol standards

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).
The IrSimple protocol improves IrDA transfer throughput as compared with existing IrDA protocols for large files, including high-resolution JPEG picture files, MP3 and WMA music files and AVI, WMV and 3G video files.
It is able to achieve a throughput as high as 90%.
For example, at the 4Mbit/s FIR (fast infra-red) datarate, existing IrDA protocol might achieve a data transfer rate of 2Mbit/s, whereas the IrSimple protocol would attain up to 3.6Mbit/s.

IR transceiver slims down to fit latest PDAs
Agilent Technologies has announced a new serial infra-red (SIR) transceiver that is ideal for new-generation personal information devices, such as PDAs, which are becoming increasingly thinner.
"Avago is currently the only company supporting the IrSimple IrDA global standard with a complete hardware and software solution", said Chee-Kien Lim, Worldwide Business Manager for Infrared Products in Avago Technologies' Optical Communication Solutions Division.
"IrSimple represents the missing link for digital cameras, camera phones and PDAs by instantly connecting enabled devices for extremely fast file transfer without the complications and lack of security inherent with other wireless technologies".
With IrSimple, users can quickly and easily ("point and shoot") transmit images from a camera phone, PDA or digital still camera to a colour photo printer or a television for immediate viewing.
Users can also enjoy fast data transmission between two mobile devices.
IrSimple allows business travelers to make slide presentations directly from their PDAs or smart phones to infra-red-equipped projectors, eliminating the need for notebook PCs and associated cables.
Avago's IrSimple solution has been tested and verified at all standard speeds.
It supports SIR (serial infra-red, 115Kbit/s), MIR (medium infra-red, 1.152Mbit/s), FIR (fast infra-red, 4Mbit/s), and VFIR (very fast infra-red, 16Mbit/s).
It also supports UFIR (ultra fast infra-red, 100Mbit/s) and a frame size of up to 32Kbyte.
Avago's IrSimple Protocol can be implemented in a wide variety of consumer devices because it supports both bidirectional and unidirectional profiles.
To use IrSimple with existing IrDA protocols, Avago offers its HSDL-S101 IrOBEX (infra-red object exchange) v.
1.3 and HSDL-S100 IrDA protocol stack, which have been installed in numerous mobile devices.
Avago supplies the ASDL-S900 IrSimple source code in standard ANSI-C programming language, making it portable to a variety of platforms.
Avago Technologies' ASDL-S900 IrSimple protocol software is available now through Avago's direct sales channel and worldwide distribution partners. Request a free brochure from Avago Technologies ...
