Avago2.4G無線/有線LED光學鼠標設計分享

ADNS-7050介紹：

       Avago公司的ADNS-7050（ADNS-7050數(shù)據(jù)手冊）光學傳感器是基于新的LaserStream技術，包括圖像采集系統(tǒng)（IAS），數(shù)字信號處理器（DSP）和一個四線串口。ADNS-7050傳感器的工作電壓為2.7V-3.6V，并可自我調(diào)節(jié)，還具備延長電池使用壽命的節(jié)電模式。它可以實現(xiàn)每秒高達20英寸的移動探測能力、高達8G的加速度及可選的每英寸400和800cpi的分辨率?？蓮V泛應用在激光鼠標，光學跟蹤球，綜合輸入設備和以電池為能源的輸入設備。

ADNS主要特性：

New LaserStream technology
Self-adjusting power-saving modes for longest battery life
Speed motion detection up to 20 ips and 8G
Enhanced SmartSpeed self-adjusting frame rate for optimum performance
Motion detect pin output
Internal oscillator – no clock input needed
Selectable 400 and 800 cpi resolution
Wide operating voltage: 2.7 V-3.6 V nominal
Four wire serial port
Minimal number of passive components
Laser fault detect circuitry on-chip for Eye Safety Compliance

ANDS-7050應用：

Laser mice
Optical trackballs
Integrated input devices
Battery-powered input devices
The ADNS-7050 sensor along with the ADNS-6120 or ADNS-6130-001 lens, ADNS-6230-001 clip and ADNV-6340 VCSEL form a complete and compact laser mouse
tracking system. There is no moving part, which means high reliability and less maintenance for the end user. In addition, precision optical alignment is not required, facilitating high volume assembly.
