苹果硬件设计

硬件接口本章描述ipod主要型号以及iphone接口信号，针脚安排以及无限标准。

30针接头：ipod和iphone底部的30针接口是产品的主要硬件接口，下标列出其针脚的接线介绍（部分针脚在ipad产品上略有出入）30针接口功能30针接口包括了一个USB接入功能，此功能将会在下文描述。

更详细的关于USB2.0的资料请参考USB协会网站资料。

ipod为配件设备提供了一个USB接口，这个接口允许配件通过iap协议，使用USB人体界面设备与ipod进行通讯。

配件本身可能会为iphone或者ipod touch提供内置的或者外接的电源供应，这些供电方式必须与“iphone及ipod touch电源要求”一致，以免对触摸屏感应器造成干扰。

此外，电源的提供也要按照“电器测试及确定”中的标准相符。

通过USB为ipod供电如果一个配件设备为通过pin8为ipod提供外部电源，而设备本身并不通过iap与ipod进行通信，也不直接把ipod 接入到电脑的USB断开，配件的30针接口比寻按照下表所示为pin4和pin6接入相应的电阻。

500ma充电方式仅仅适用于特定的电池包产品，并且在正式应用于配件之前必须得到苹果公司的同意。

以下的ipod及iphone机型兼容于上面所述的10.5瓦充电方式：配件提供最大1A输出电流充电的，输出电压不能低于4.75V；配件提供最大2.1A输出充电的，当输出电流低于1A时，电压不低于4.75V，当输出电流为1A——2.1A，输出电压不低于4.6V。

为ipod及iphone充电的产品应该尽量采用1A输出，而为ipad提供充电的产品必须选择2.1A输出。

否则将会导致无法充电或者充电过慢。

无论选择任何一种输出电流，在对ipod或者ipad充电的过程中必须保证此最大电流在充电全过程当中是一直可得。

充电器在被接入到ipod iphone 或者ipad时，以上四个电阻必须一直能被检测得到，因为这些电阻决定了配件对ipod的输出电流大小。

iPod接口中文说明

iPod附件界面协议说明书此协议描述的是第三代iPod（第一款用到30脚连接器的iPod），iPod mimi，第四代iPod，iPod photo，iPod nano，第五代iPod的特性。

该文档中讲述的内容不适用于第一、第二代iPod与iPod shuffle。

1．连接器引脚说明：30连接器的引脚说明见下表1：注意：“Remote Sense”脚的功能是减少模拟音频与模拟视频输出间的色度亮度干扰。

该引脚的接法如处理不好将会产生不良的效果。

（色度、亮度干扰）9脚（音频/遥控）连接器（略）2．功能描述该节描述30脚连接器与9脚连接器的功能特性。

不同iPod型号实际功一、30脚连接器该节讲述30脚连接器的性能及物理特性。

1．FireWire 充电对于新开发的iPod附件，我们强烈建议通过USB线进行充电代替FireWire充电。

对于30脚连接器中的FireWire充电脚，需要8到15伏的电压，8W的功率。

2. USB2.0如果只用USB线进行充电而不用来进行数据传输，D+、D-脚不能悬空具体接法如下。

如果某一装置的USB输出提供500mA的电流，接法如图1。

如果提供1000mA的电流，接法如图2。

（图中电阻误差均为1%）图1图23．附件检测与识别总的来说，我们可以将iPod附件分为两类：一类是利用iPod协议的附件，可以与iPod进行通信的。

另一类是基于电阻的附件，需要达到特定的功能。

基于电阻的附件使用一个“识别电阻”去达到特定的功能，该电阻的接法如图3，不同的电阻相应的功能如表3。

图3R阻值附件功能异常现象3．01K 简单的第三、四代iPodDOCK 当连接时，第三、四代iPod,iPodmini会哗哗响191K 通过USB进行通信使USB通信变成默认设置255K 电池塞满附件不能对iPod充电，iPod会显示电池已满549K 同步通信没异常现象1M 汽车充电器当USB或FireWire移开时，iPod会暂停注意：当使用导线去连接连接器时，应考虑导线的长度，确保第十脚的电压在你想要的电压范围内。

Apple iPod,iPad and iPhone dock Connector Pinout 30pin connector used on the dock station for iPod,iPad and iPhone.Nano).This connector is used on iPod(starting from3rd generation),iPad andiPhone.It is used to connect the iPod or iPhone to various devices:PC(via USB or FireWire IEEE1394),audio amplifier,serial deviceNotes•Signals with grey background may not exist on some docking stations.•Apple serial devices(i.e.iTalk and remote control)communicate with iPod(3rd generation or more) using the Apple Accessory Protocol.•The serial connection uses a standard19200baud8N1protocol(the speed can be increased up to 57600but tends to become unstable).Back side of dock connector;246810121416182022242628301357911131517192123252729Pins1,2connected on motherboard.Pins15,16connected on motherboard.Pins19,20connected on motherboard.Pins29,30connected on motherboard.If you disassemble the original apple-ipod-dock-connector-cable and look at the connector itself,on the back side,where it is soldered,you can see the number1and30(e.g.pin1and30).In this description NUMBERING is INVERSED:pin1is pin30and pin29is pin2,so,don't look at numbers on connector.The remote control,iTalk and other serial devices use Apple Accessory Protocol for communication with iPod.This protocol was introduced with the3rd generation iPods,and is also compatible with the4th generation iPods and mini iPods.The connections uses a standard8N1(one startbit8data bits1Stopbit) serial protocol,19200baud(higher rates up to57600also possible,but speed faster than38400may cause problems with large amounts of data),delay of12microseconds inserted between end of the stopbit and the beginning of the next startbit(also working without this delay).Electrical:high+3,3V low0Vdefault line state:high.Codes used for communication with peripherals are hereThis device may be connected to the firewire computer port by straight cable(TPB+/-,TPA+/-should be twisted pairs in cable)iPod Nano4th Genno longer will charge from12volts on the firewire pins.If you tie pins25and27 together and then connect a10kΩresistor to+/-5volts to pins23and15(or16)then it will charge.If you don't tie25and27together,it won't charge.iPod Touch3G:may also require for pins1and2(GND and audio out GND)to be connected in order to output audio(pin11to GND).Works with appr.500kΩbetween pin21and GND.iPod Touch2G requires pin11connected to15/16,then connect that to pin21with a68kΩresistor to use the audio line out.This is because the device needs to be told to redirect the signal to the Line Out pins rather than to the built-in speaker.This explains why certain accessories won't work with the iPod Touch 2G and maybe even the iPod Touch3G.The Nano5G will require the pin11connection but not the68kΩresistor for redirecting audio.Nano5G:connecting the68kΩresistor to ground will disable the audio redirection accomplished by connecting pin11to ground.You may need to ensure1and2are connected to GND for proper charging to occur.。

苹果数据线的原理

苹果数据线的原理
苹果数据线包含几种不同的线路，提供电源和数据传输功能。

苹果数据线包括一个USB连接器和一个Lightning或30-Pin连接器。

USB连接器插入电脑或充电适配器，而Lightning或30-Pin连接器插入苹果设备。

苹果数据线的原理如下：
1. 电源线路- 这是数据线中使用的第一根线路，用于提供所需的电源。

这条线路连接到USB连接器上的电源针脚，将电源传输到苹果设备上。

2. 数字信号线路–这条线路用于数字数据传输。

Lightning连接器使用了8个线路（4个用于输出，4个用于输入），而30-Pin连接器使用了30个线路（最初只有16个用于数据传输）。

这些线路用于传输音频、视频、照片、文档和其他数据。

3. 地线–苹果数据线的第三条线路是地线，用于接地和保护设备。

除了以上三个基本线路，苹果数据线还包括一些电路和电子元件，这些元件可确保数据的传输速度和质量。

数据线中还内置了电路板，其中包括控制信号和转换电源的元件。

总之，苹果数据线通过电源线路，数字信号线路和地线，提供了数字数据的传输
和充电功能。
