DS90UB981-Q1: 串行器DS90UB981 与解串器DS90UB688 FPDLINK 4 配置问题。串行器内置型给解串器，解串器数据引脚无波形

xu gang

你好，老师，目前遇到问题。串行器DS90UB981 通过(FPDLINK 4 )同轴线相连解串器DS90UB688. 解串器 WriteI2C(688_ADDR, 0x31, 0x85/0X87); //FPD4_RX_CFG 配置强制单链路/自动 Port0, 端口0/1 FPD4使能。串行器配置成WriteI2C(981_ADDR, 0x05, 0x0b); ，串行器和解串器就LINK 不上，通过I2C 通过981透传去控制688 ，I2C也不通,UB688 LOCK引脚也为低电平，但是 ub688解串器 WriteI2C(688_ADDR, 0x31, 0xe7); 就可以LINK I2C也透传OK ，解串器688,引脚LOCK 也为高电平。请问UB688 寄存器0X31 具体怎么配置。文档Bit5/bit6 是预留没有说明。按照解串器0X31配置为0xe7 串行器 0X05配置为0x0b , u688LOCK引脚为高电平。(串行器配置内置Pattern通过DOUT0+/DOUT0-),UB688 CH0 CH1 通道只有时钟有波形，数据引脚没有波形。这是我配置串行器参数DS90UB981初始化.txt 请问是怎么回事。帮指点一下，解串器UB688 这边需要怎样配置？谢谢

我目前还在对此进行审查，所以明天会向您更新情况。在此期间，您能否再次确认一下您是如何设置 SER 寄存器 0x5 的？看起来您将其设置为 0xB 的值，但根据您的描述，我认为您可能想要将其设置为 0x2C 而不是 0xB。当您将其设置为 0xB 时，会缺失第 0 和第 1 位，所以设置并不正确。
从总体上看，如果绑带安装正确，这些设备应该会自动锁定。我会查看原理图，同时也会检查您添加的初始化脚本以及绑带的情况。

老师你好，我写错了，我忘了写往左偏移2, 就是写0x2c 。请问我提供的参数还有其他地方有问题吗？解串器UB688 0x31 配值多少？

这些图纸之前是否曾提交过以供审查呢？我仔细查看后发现了一些不太正常的地方。
首先，我认为您遇到锁死问题的原因在于 688 板上的 MODE_SEL0 端口连接的电压分压电路存在错误。该端口的上拉电阻为 30 千欧姆，下拉电阻为 18 千欧姆。这样就形成了 0.375 的电压比，这与 MODE_SEL0 的任何选项都不匹配。请您让客户将此设置更改为使用推荐的电阻组合之一。
其次，从这些截图来看，似乎 I2C 线路上并没有任何上拉电阻。有可能它们位于电路图的其他部分，但我并未看到它们与任何设备相连。

将此寄存器设置为 0xE5 或 0xE7 是可以的；然而，这并非获取锁的推荐方法。获取锁的最佳方式是设置正确的锁带值，并允许设备自动锁定。

这似乎是一份全新的编写好的脚本。对于 FPD4 设备的编程和初始化操作，应使用我们的 ScriptGen 工具来生成初始化脚本。这样就能根据客户提供的信息生成一个包含所有正确顺序和寄存器写入操作的 Python 平台脚本。

老师硬件改过来，参数配置需要如何配？能否检查我的ds90ub981初始化.TXT 是否正常，不正确，能否修正一下。

这是我生成的初始化脚本，请查看文件中的文本标题部分，如果发现有任何错误请告知我，同时请确认能否使其正常运行。

老师你好，现在参数981输入内置信号给UB688 可以显示，但是目前有个问题就是显示画面下边有一些虚像在斗都动，我想看下是981信号问题，还是UB688的问题，现在我想UB688自出内置彩条，在你配置的基础上，我配置了一组688参数内置Pattern

从文本格式来看难以判断，但至少可以确定的是您似乎没有设置 HSYNC 和 VSYNC 的极性。我已经为仅用于 DES PATGEN 的部分重新生成了一个新脚本：

If you want to play with the timings to figure out the ghosting issue, you can edit lines 128 through 152. Let me know if the issue is still there with DES PATGEN and I can help debug from there.
