解读MIPI C-PHY D-PHY子系统 权衡利弊，挑战和采纳 About the Author:   Ashraf Takla President & CEO, Mixel, Inc. 2018年4月首次发布。于2022年3月更新。 MIPI® C-PHY(SM)于2014年10月面世，让人既兴奋又担忧。这个新的C-PHY与MIPI D-PHY(SM)和M-PHY®相比如何？MIPI C-PHY有什么不同，它是否与D-PHY足够兼容，以便两者可以在一个混合子系统中共存？ 多年后的今天，答案已经很清楚了。 本文将阐述这些答案，提供D-PHY和C-PHY架构的高层次概述，突出其相似性和差异性，确定每种PHY的优点和缺点，并提供在实施C-PHY时遇到的一些挑战的见解。最后，我们将研究Mixel®对C-PHY/D-PHY组合IP的创新实现，从多个来源获得的硅结果，涵盖使用案例，并检查C-PHY/D-PHY组合解决方案在市场上的采用情况。 让我们首先仔细看看D-PHY，它自2009年以来就已经存在，因此得到了更好的理解和广泛应用。D-PHY是一种简单的源同步PHY，使用一个时钟通道和不同数量的数据通道。四个数据通道的D-PHY的框图如图1所示，每个通道的细节如图2所示。由于D-PHY在市场上已经存在了近十年，因此有丰富的文献涵盖了它的独特功能和使用情况（1）。 Figure 1: Four data lane D-PHY block diagram Figure 2: Block Diagram of a D-PHY data lane 相比之下，C-PHY是一种更新、更复杂的PHY。它在三个信号上运行，三合一，时钟被嵌入到数据中，从而不需要单独的时钟通道。 C-PHY的框图如图3所示。 Figure 3: C-PHY Block Diagram 表1对D-PHY和C-PHY进行了比较。Read more →
