ADNS-5000 Optical Mouse Sensor Data SheetDescriptionThe ADNS-5000 is a one-chip USB optical mouse sensor for implementing a non-mechanical tracking engine for computer mice.It is based on optical navigation technology that measures changes in position by optically acquiring sequential surface images (frames) and mathemati-cally determining the direction and magnitude of move-ment.The sensor is in a 18-pin optical package that is designed to be used with the ADNS-5100 Round Lens or ADNS-5100-001 Trim Lens, the ADNS-5200 Clip, and the HLMP-ED80-XX000 LED. These parts provide a complete and compact mouse sensor. There are no moving parts, and precision optical alignment is not required, facilitating high volume assembly.The output format is USB. This device meets USB revision1.1 specifications and is compatible with USB Revision2.0 specification.Default resolution is specified as 500 counts per inch, with rates of motion up to 16 inches per second and 2g acceleration. Resolution can also be programmed to 1000 cpi. Frame rate is varied internally by the sensor to achieve tracking and speed performance, eliminating the need for the use of many registers.A complete mouse can be built with the addition of a PC board, switches, mechanical Z-wheel, plastic case and cable. A 1% pull up resistor is needed for the USB port to signify a low speed HID device.Featuresx Optical navigation technologyx No mechanical moving partsx High reliabilityx Complete 2-D motion sensorx High speed motion detectionx Accurate navigation over a wide variety of surfaces x No precision optical alignment neededx Wave Solderablex IEC 60825-1 eye safe under single fault conditionsx Single 5.0 volt power supplyx Meets USB Revision 1.1 Specification and compatible with USB Revision 2.0 specificationx Meets HID Revision 1.1x On Chip LED Drive with regulated current Applicationsx Mice for desktop PC’s, Workstations, and portable PC’sx TrackballsxIntegrated input devicesFigure 1. Package outline drawing (top view)Theory of OperationThe ADNS-5000 is based on Optical Navigation Technol-ogy. It contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP) and USB stream output.The IAS acquires microscopic surface images via the lens and illumination system provided by the ADNS-5100 Round Lens or ADNS-5100-001 Trim Lens, ADNS-5200, and HLMP-ED80-XX000. These images are processed by the DSP to determine the direction and distance of mo-tion. The DSP generates the 'x and 'y relative displace-ment values which are converted to USB motion data.PinoutPin PinDescription1 D +USB D+ line2 D -USB D- line3ZA Scroll wheel quadrature input 4ZB Scroll wheel quadrature input 5LGND LED ground 6XYLED XYLED Input7VDD5 5 Volt Power (USB VBUS)8GND System ground 9REG0 3 Volt Power 10VDD3 3 Volt Power11OPT 0Descriptor Select 1 or B412OPT 1Descriptor Select 2 or B513GND System ground 14OSC_IN Ceramic resonator input 15OSC_OUT Ceramic resonator output 16B3Button 3 input (switch to ground)17B2Button 2 input (switch to ground)18B1Button 1 input (switch to ground)11 OPT 0 (B4)12 OPT 1 (B5)15 OSC_OUT14 OSC_IN13 GND18 B117 B216 B310 VDD3GND 8VDD5 7ZB 4LGND 5XYLED 6D+ 1D- 2ZA 3REG0 9Figure 2.

Recommended PCB mechanical cutouts and spacing (Top view)The components interlock as they are mounted onto defined features on the base plate.The ADNS-5000 sensor is designed for mounting on a through hole PCB, looking down. The aperture stop and features on the package align it to the lens (See figure 3).The ADNS-5100 Round lens provides optics for the imag-ing of the surface as well as illumination of the surface at the optimum angle. Lens features align it to the sensor, base plate, and clip with the LED. The lens also has a largeFigure 5. Exploded view drawinground flange to provide a long creepage path for any ESD events that occur at the opening of the base plate (See figure 4).The ADNS-5200 clip holds the LED in relation to the lens. The LED must be inserted into the clip and the LED’s leads formed prior to loading on the PCB.The HLMP-ED80-XX000 LED is recommended for illumi-nation. If used with the bin table, sufficient illumination can be guaranteed.Block DiagramFigure 6.

Bend the LED leads 90 degrees and then insert the Led into the assembly clip until the snap feature locks the Led base.3. Insert the LED/clip assembly into PCB.4. Wave solder the entire assembly in a no-wash solder process utilizing solder fixture. The solder fixture is needed to protect the sensor during the solder process. The fixture should be designed to expose the sensor leads to solder while shielding the optical aperture from direct solder contact.5. Place the lens onto the base plate.6. Remove the protective Kapton tape from optical aperture of the sensor. Care must be taken to keep contaminants from entering the aperture. Recom-mend not placing the PCB facing up during the entire mouse assembly process. Recommend to hold the PCB first vertically for the Kapton removal process.7. Insert PCB assembly over the lens onto base plate aligning post to retain PCB assembly. The sensor ap-erture ring should self-align to the lens.8. The optical position reference for the PCB is set by the base plate and lens. Note that the PCB motion due to button presses must be minimized to maintain optical alignment.9. Install mouse top case.Figure 7.

The ADNS-5000 will re-send the last packet if the transfer is not acknowledged properly.USB COMMAND DETAILS___________________________________________________________________________________________USB_RESET D+/D- low for an extended periodUSB Spec: A device may reset after seeing an SE0 for more than 18.6 uS, and definitely after 10mS. Notes: After power up and prior to Reset, the device will not respond to any USB commands. After the device has been given a USB Reset, the device’s address will be reset to zero and the device will be in the Default state. The chip will default to Report protocol and any pending output will be flushed.___________________________________________________________________________________________USB_SUSPEND Idle state for an extended period USB Spec: A device may suspend after seeing an idle for more than 3mS, and definitely after 10mS. Notes: The chip will take a minimum of 5mS to start Suspend, though will definitely start after 6mS. The chip may finish the current frame if necessary before stopping the clock. Thus, an additional frame time may be used to reach Suspend mode.___________________________________________________________________________________________USB_RESUME Non-idle state USB Spec: Remote Resume signalling from a device must be between 1mS and 15mS. The host is required to send Resume signaling for 20mS plus 10mS of resume recovery time in which it does not access any devices. This allows devices enough time to wake back up.

总的来说，新款的G502 HERO采用了高性能的自家HERO传感器和欧姆龙50M，性能较前代有一定升级；同时有延续了老款产品舒适的手感和优良的设计，可谓是目前非常不错的一款高端有线游戏鼠标。

从实际体验来看，上手之后的G502 HERO在游戏当中表现优秀，集合自定义按键和RGB灯效，可以带来让人心动的游戏体验。

工程师点评DETAILS参数表传感器：HERO分辨率：100~16000dpi最大加速度：＞40G最大速度：＞400IPSUSB报告速率：1000Hz/ms 尺寸：132mm×75mm×40mm 重量：121g配重：5×3.6g线长：2.1m耐用性：5000万次（主按键）参考价格：549元科幻真英雄罗技G502 HERO游戏鼠标罗技旗下的G系列游戏鼠标一向是玩家的最爱，其中2014年推出的G502更是以颠覆性的外观设计以及PMW3366传感器的优秀性能而受到了玩家的欢迎。

随后推出的RGB版只能算是G502的小迭代，4年前的神作在今天看来已经显得略有些老了。

而罗技新推出的G502 HERO，可谓是这款神作的正式升级版本，在保持外观设计和手感的同时，采用了罗技自家的HERO传感器，将分辨率从12000dpi升级到了16000dpi，更适合游戏玩家操作。

那么，这款新品究竟表现如何呢？118EXPERIENCE119顾名思义，罗技G502 HERO最大的变化就是将基于原相PMW3360深度优化的PMW3366传感器更换为了罗技自家的HERO传感器，而新鼠标的最大改变也是基于HERO传感器实现的。

G502 HERO 拥有100~16000dpi的分辨率，最大加速度超过40G，最大速度超过400IPS，和之前推出的无线版G PRO一致。

尽管罗技自研HERO传感器的初衷是为了降低功耗，改进无线鼠标的续航，但是在性能已经不属于外采产品的情况下，在有线鼠标上使用自家HERO传感器可以实现平台一致性，有助于软硬件的协同优化。

微软光学红光鲨（Microsoft IntelliMouse Optical）简称IO 在任何版本官方零售版的盒子和底盘标贴上印的产品名称都是IntelliMouse Optical 。

IO1.1这个俗称应该来自于IO的oem版本，因为oem版本底盘标贴上印的产品名称是IntelliMouse Optical 1.1A一，IO诞生的历史背景2001年中期，随着第二代IntelliEye光学引擎技术的成熟，微软硬件发布了两款针对高端办公用户的旗舰级产品微软光学银光鲨3.0(简称IE3.0)和被称为IE3.0平民版的微软光学红光鲨（简称IO）。

与IE3.0专为右撇子设计不同的是，IO采用了左右对称的设计，满足了不同用手习惯人的需求。

相对于传统机械鼠标当时的人们已经逐渐接受了定位更加准确且无需清洗，表面适应能力更强的光电鼠标，但丢帧问题一直是困扰光电鼠标的顽疾。

基于第二代IntelliEye光学引擎开发的IE3和IO两兄弟，率先将扫描频率提高到6000次/秒并将这一顽疾一扫而光，可以说IE3与IO是真正第一款做到不丢帧的光电鼠标。

据悉，正是因为IE3与IO的面世，作为微软老对手的罗技才迫不及待的推出了搭载兼容性并不成熟的MX光学引擎的两款产品MX300和MX500。

二，IO相关技术指标核心：IntelliEyeDPI：400刷新率：6000次/秒（已经确认07年以后的IO均为9000fps）最大加速度：25G最大速度：54IPS支持系统：WINDOWS、MAC（从X800以后盒子上增加支持Vista系统标志）连接方式：USB/PS2驱动支持：Intilli Point4.0以上（最新版本为Intilli Point 6.31 For WinXP-64/Vista-64）微动开关：三个主键采用OMRON长方形微动，两个侧键采用Panasonic方形微动。

其他：5个可自定义按键、左右对称设计、刻度滚轮三，特点分析1.优点a 游戏中的出色性能正所谓时势造英雄，连微软自己都没有想到作为针对高端办公用户设计的IO和IE3.0能够在游戏领域取得空前的成功，而这一切都要归功于一款fps游戏Counter-Strike。

2、测量键盘、鼠标接口的数据线（第1脚）和时钟脚（第5脚）
的对地阻值，正常阻值应为600Ω左右。

游戏鼠标光学引擎分析鼠标引擎，做为鼠标中最为核心的部件，是鼠标性能壮大与否的关键，由于各类缘故，消费者关于鼠标引擎这一核心部件知之甚少，造成了现在一些品牌游戏鼠标产品以次充好的现象，而消费者却不明白。

耗时半年，参阅众多官方文献，并与资深设计人员进行沟通，ZOL将历史第一次整理并详解——目前市面有售的经典游戏鼠标的引擎，为广大网友提升选购产品和鼠标知识做出奉献。

本文将按游戏鼠标引擎的推出时刻为主线，对各大游戏鼠标引擎性能参数进行详细解析。

[中关村在线键鼠频道原创]游戏鼠标，一个随着本世纪初电脑普及和PC游流行而诞生的事物，从光机时期的BOOMSLANG系列开始，游戏鼠标就被广大的PC游戏爱好者和职业电竞选手所追捧。

而的诞生，更是将光学鼠标因漂移丢帧而不适合进行游戏的现象一举打破。

从此以后，光学游戏鼠标一统天下，MX510，响尾蛇等新品层出不穷，各大厂商各展所长将游戏鼠标又进展到一个全新的高度。

而在07年的时候以铜斑蛇为代表的一批激光引擎游戏鼠标的显现将游戏鼠标的进展又带入一个新的领域。

时至今日，各类游戏鼠标层出不穷，价钱也从几十元到数百元不等。

之间的差距，除品牌、做工、用料之外，最明显的不同确实是鼠标所采纳的光学引擎的不同，那么不同的光学引擎，不同在那里哪？主流游戏鼠标和山寨游戏鼠标性能上有那些不同哪？笔者将分两期就主流游戏鼠标光学/激光引擎性能做出详细解析。

IntelliEye2引擎与2001年：第一款游戏级光学引擎 IntelliEye2引擎说到鼠标光学引擎，不能不提的确实是微软硬件于2001年推出的鼠标上所采纳的IntelliEye2引擎。

其凭借着每秒6000帧的刷新率一举打破了昔时光电鼠标丢帧和表面兼容性差的特点。

作为微软硬件和ST 强强联合的产物，IntelliEye2引擎除拥有高达6000帧/秒的刷新率之外，其它参数都并非出众，400CPI 的采样率和22×22的CMOS 点数即便在昔时来看也较为一样。
