San Jose, Calif. Avago Technologies has launched two high-precision, small-form-factor laser navigation sensors for corded and cordless PC mice. Based on Avago's LaserStream technology, the ADNS-7530/7550 navigation sensors come complete with several lens options. These navigation sensors enable mouse designers to develop mice that are easy to use and provide precise tracking on a broad range of surfaces.
The ADNS-7530/7550 navigation sensors provide high-speed motion detection up to 30 inches per second (ips) and 8 g, an on-chip oscillator and integrated Vertical Cavity Surface Emitting Laser (VCSEL) to minimize the number of components required for the design. The devices feature selectable 400, 800, 1200, and 1600 cpi resolution. These laser sensors also use coherent light and interference to reveal fine surface features to enable computer mice to track accurately on a broad range of surfaces.
The ADNS-7550 series is suitable for corded applications such as corded mice for PCs, trackballs and input devices. The ADNS-7530 series delivers a lower power architecture with automatic power management modes, making it well-suited for use in cordless applications such as miniature travel mice and cordless input devices. Both devices measure 16.2 (L) x 10.1 x (W) by 3.96 mm (H).
The ADNS-7530/7550 devices contain an image acquisition system (IAS), a digital signal processor (DSP), and four-wire serial port interface (SPI) support. The IAS acquires microscopic surface images via the lens and illumination systems. These images are then processed by the DSP and determine the direction and distance of motion. The design architecture uses Avago's patented LaserStream optical mouse technology, which provides accurate and precise tracking on a broad range of surfaces especially on smooth surfaces like photo paper, black painted surfaces and tiles.
Three different lens options are available for the ADNS-7530/7550 devices to enable designers to design in the new package without having to change the existing mouse base plate. The lens options include a small-form-factor lens (ADNS-6150), a trim lens (ADNS-6160-001) and a wide trim lens (ADNS-6170-002).
Pricing: Starts at $2.50 each in high volume.
