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.
This input device solution simplifies continuous scrolling and navigation of long lists or menus with the use of only one hand - making it an ideal solution for portable handheld devices.

With the demand for mobile music projected to grow rapidly from 20% of total phone shipments in 2006 to 50% by 2009, a mobile phone with integrated music player capability has become an extremely popular feature.
Today's users often complain about the difficulty of navigating long play lists with the conventional rocker switches used in today's phones and music players.
With the ease of variable speed control, Avago's scrollwheel is an ideal replacement for those switches, and its integrated illumination ring offers a more visually attractive addition to a front panel.
The Avago AMRX-1500 scrollwheel device is built around Avago's reliable reflective optical technology.
The horizontal scrollwheel provides a two-channel quadrature output, with resolution of 45 cycles per revolution.
It operates from a single 2.4 to 3.3V supply, and provides a single-ended 1.8V CMOS logic compatible output.
It is easy to assemble, featuring plug-and-play connectivity through a flexible printed-circuit board, and requiring no signal adjustment.
To maximise battery life, the device features a power-down mode in which it draws only 4uA.
The Avago AMRX-1500 is RoHS-compliant and lead-free.
The Avago Technologies AMRX-1500 scrollwheel provides customisable aesthetic design with choices of colour, finish, material and illumination colour to complement the overall look and feel of handheld devices.
