Avago Technologies Announces New Miniature Optical Finger Navigation Input System for Cell Phones and Portable Electronic Devices

Building on its optical navigation sensor technology that was pioneered in 1997, Avago’s OFN features a low-power architecture and power management modes, making it ideal for use in battery- and power-sensitive applications. Moreover, it is capable of high-speed motion detection of up to 15 inches per second. It also has an on-chip oscillator and integrated LED to minimize external components. Due to the fact that there are no moving parts in this OFN solution, end-users benefit from a device that is highly reliable and requires little or no maintenance. Additionally, precision optical alignment is not required – enabling high volume assembly.

Since 2007, all major cell phone manufacturers have begun to replace 5-way rocker switches and trackballs with OFN solutions. With the successful adoption of OFN, manufacturers are now shipping millions of cell phones and other handheld electronic devices to customers throughout the world with this innovative technology. To date, Avago has shipped a combined total of over a billion optical navigation sensors to a wide range of global customers.
