Avago Technologies Miniature Optical Finger Navigation Input System
Avago Technologies developed a new miniature optical finger navigation (OFN) input system for mobile and consumer electronic devices. The OFN solution is user-friendly and features a low-power architecture and power management modes. The optical finger navigation is ideal for designers of electronic devices such as mobile phones, MP3 players, ultra-miniature PCs, game pads, digital cameras, and keyboards.
Avago Optical Finger Navigation Features
- Low power architecture
- Surface mount technology device
- Self-adjusting power-saving modes for longer battery life
- Self-adjusting frame rate for optimum performance
- Motion detect pin output
- Internal oscillator — no clock input needed
- Selectable 250, 500, 750, 1000 and 1250 cpi resolution or auto
- Dual 2.8V/1.8V or single 2.8V supply options
- Selectable Input/Output voltage at 2.8V or 1.8V nominal
- Serial peripheral interface (SPI) or Two wire interface (TWI)
- Integrated chip-on-board LED compliant to eye safety standards

Avago’s OFN is ideal for use in battery- and power-sensitive applications. It is capable of high-speed motion detection of up to 15 inches per second (ips). 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. In addition, precision optical alignment is not required — enabling high volume assembly.
