Laser Gaming Sensor
The ADNS-9800 Laser gaming sensor comprises
of sensor and VCSEL in a single chip-on-board (COB)
package. ADNS-9800 provides enhanced features like pro-
grammable frame rate, programmable resolution, config-
urable sleep and wake up time to suit various PC gamers’
The advanced class of VCSEL was engineered by PixArt
Imaging to provide a laser diode with a single longi-
tudinal and a single transverse mode.
This Laser gaming sensor is in 16-pin integrated
chip-on-board (COB) package. It is designed to be used
with ADNS-6190-002 small form factor (SFF) gaming laser
lens to achieve the optimum performance featured in this
document. These parts provide a complete and compact
navigation system without moving part and laser calibra-
tion process is NOT required in the complete mouse form,
thus facilitating high volume assembly.
Theory of Operation
The sensor is based on Laser technology, which
measures changes in position by optically acquiring
sequential surface images (frames) and mathematically
determining the direction and magnitude of movement.
It contains an Image Acquisition System (IAS), a Digital
Signal Processor (DSP), and a four wire serial port. The IAS
acquires microscopic surface images via the lens and il-
lumination system. These images are processed by the
DSP to determine the direction and distance of motion.
The DSP calculates the Δx and Δy relative displacement
values. An external microcontroller reads the Δx and Δy
information from the sensor serial port. The microcon-
troller then translates the data into PS2, USB, or RF signals
before sending them to the host PC or game console.
