Cypress公司的OvationONS传感器CYONS1001x系列是高精度和高性呢个的激光导航传感器，具有无与伦比的速度和精度以及低功耗。该系列传感器集成了检测器和激光与卡入式镜头（snap-on lens）设计，只持全速（50英寸/秒）和全分辨率（2800计数  /英寸），它的取样速率高达40 kHz，具有即时响应性能，因而广泛应用在高性能游戏，精密的图形设计以及高精度定位检测。本文介绍了OvationONS传感器CYONS1001x系列的主要性能，方框图，所推荐的电源和接地电路图，以及有线鼠标参考电路图和无线鼠标参考电路图。

The OvationONSTM CYONS1001x laser navigation sensors are breakthrough solutions for wired and wireless mice, and precision motion-sensing applications. Built around Cypress Semiconductors patented OptiCheckTM laser technology, these devices offer a variety of significant advantages.
Unlike any other laser-based sensor on the market today, the CYONS1001x sensors provide:

■ the unique ability to maintain full resolution at speeds up to 50 inches per second (ips)
■ low power consumption regardless of tracking speed or resolution
■ an unprecedented 40 kHz positioning sampling rate
As a result, the CYONS1001x sensors deliver fast, precise, responsive tracking, without the trade offs between power and performance that characterize traditional image-correlation sensors.
Moreover, the CYONS1001x sensors are strategically designed to simplify assembly, reduce manufacturing costs, and improve yield. The sensor IC, vertical-cavity surface emitting laser (VCSEL), and laser driver are integrated in a single 8x8 QFN package with a self-aligning snap-on lens. Laser output power is calibrated before shipment to meet eye-safety standards.

Consequently, there is no need for laser handling, laser power calibration, or optical alignment.

Five versions of the CYONS1001x sensor are available, each with features designed for its target application. Optimized for gaming and other specialized high-performance applications, the CYONS1001U, CYONS1001G, and CYONS1001 combine unrivalled effective cursor speeds with continuously variable resolution to 3200 counts per inch (cpi) and independent resolution control in the x and y directions. The general purpose CYONS1001L and CYONS1001T, designed for desktop mouse and trackball applications, support two self-adjusting power down modes for extended battery life.

All CYONS1001x sensors provide maximized counts per second, minimized latency to motion changes, and optimum signal quality in the detection of laser-speckle signatures over a wide range of surfaces, offering users the ultimate experience of fast, precision tracking.
