Cirrus Logic has announced a development kit for hardware developers to make Lightning versions of audio hardware designed for the analog 3.5mm tip/ring/sleeve (TRS) or tip/ring/ring/sleeve (TRRS) connector, reports Apple Insider.

凌云逻辑公司
据苹果内幕消息网报道，凌云逻辑公司已发布为硬件开发者制作的开发套件，该套件将用于3.5mm TRS（尖/环/空心轴）或TRRS（尖/环/环/空心轴）接口的音频硬件转换成闪电闪电接口版本。

The development kit, named the Cirrus Logic CS42L42, is aimed at hardware developers wanting an easy way to quickly develop Lightning-native headsets. The kit includes a reference design circuit board, suitable for embedding into an inline remote or similar, that combines a 114dB digital-to-audio converter (DAC) with a 35mW headphone driver and supports microphone input. The kit also provides a development board that has headers for logic probes, a 3.5mm audio jack for use with existing analog hardware, and remote buttons to aid debugging and development. As well as the hardware, it also includes a sample iOS application.
这款名为凌云逻辑CS42L42的开发套件是针对那些想要简单迅速地研制出原生闪电接口耳机的硬件开发者所设计的。套件中包括一块可嵌入耳机线控或类似硬件的电路设计模板，它将114dB 数字模拟转换器（DAC）与35mW耳机驱动器相结合，并且支持麦克风输入。该套件还提供了一个开发板，其上有为逻辑探针准备的排针，一个适配现有硬件的3.5毫米的音频接口，以及辅助调试开发的远程控制按钮。除了硬件之外，它还包括一个IOS示例应用程序。

The kit is available to developers registered in Apple's MFi ("Made For i-device") program.
这款开发套件适用于已注册苹果MFi认证项目（“Made Fori-device” 专为苹果产品设计）的开发者。

The next generation iPhone is widely believed to not include a traditional 3.5mm TRRS jack, a change that will leave it incompatible with the hundreds of millions of headphones and headsets already on the market. It's believed that Apple will ship Lightning-native headphones with the device and that adapters to allow the use of existing 3.5mm hardware will also be available.
人们普遍认为，下一代苹果手机将不包含传统的3.5毫米TRRS耳机接口，这一改变将使它与数以百万计已经上市的耳机和耳麦不兼容。据说苹果公司将随手机一同推出原配闪电耳机，并且也将推出允许现有3.5毫米硬件设备使用的适配器。

Hardware such as this Cirrus Logic part should enable straightforward conversions of current designs to make them Lightning native. This hardware also offers hints at how Lightning headphones will work: specifically, Lightning will remain a digital interface, requiring the use of an external DAC, rather than offering the ability to put analog audio over the port.This will enable the iPhone's internal DAC to be used. Even with Lightning headphones, the iPhone will have to retain its own DAC for its internal speakers.
像上述凌云逻辑公司生产的这类硬件应能使现有设备直接适配原生闪电接口。这款硬件也暗示了闪电耳机将会如何运作：具体来说，闪电接口仍然是一个需要使用外部数字模拟转换器的数字接口，而不具备通过端口模拟音频的能力。这保证了苹果手机内部数字模拟转换器的地位。即使拥有闪电耳机，苹果手机仍会为自己内部的扬声器保留它的数字模拟转换器。
