您好，

E2E工程师已回复：

请确认以以下寄存器写入以正确设置 ADC

0 user5180271 3 年多前

这些寄存器核对过了，配置得都是对的。另外发现，

0x29 CLK_CTRL0 Clock Control 0 (default: 0x80) 节 8.6.6

这个寄存器，分别配置0xf0~0xff，输出结果还是跟截图1一样的。

好的，我已将您的回复反馈给E2E工程师，收到回复后，我会在这里反馈给您

E2E工程师 Ameet有以下回复：

我对 Xilinx JESD IP 有疑问。是否有任何错误标志？我不知道为什么 CH2-CH4的数据重新排序。 ILAS 序列在所有通道上是否正确？此外，是否需要如此高的插入损耗设置？我不确定您的硬件设置，但大多数走线较短的板子应该可以使用6-8dB 的值。

我相信ramp test 模式将在每个多帧边界上重置。在这种情况下，多帧是32字节，因此它重置为0x1F。请尝试将 K 设置为64 (或将 Km1设置为63)的测试。这可能表明ramp 将增加到0x3F。我还将与 ADC 设计团队确认这种行为。

E2E工程师 Neeraj 有以下反馈：

For the register address 0x29 you mention it produces same output as screenshot 1. Can you please let me know what is the screenshot1? Setting the register 0x29 to 0xF0 enabled the SYSREF processing, Enable the sysref receiver and also enable the sysref zoom feature. The bit 3:0 for register 0x29 should be programmed after reading the sysref window postion. Please read the following paragraph from datasheet www.ti.com/.../adc12qj1600-q1.pdf to see how to program the sysref_sel.

9.3.4.4.2 SYSREF Position Detector and Sampling Position Selection (SYSREF Windowing)

对于寄存器地址0x29，您提到它将产生与截图1相同的输出。您能告诉我截图1是什么吗？将寄存器0x29设置为0xF0可启用SYSREF处理，启用sysref接收器以及启用sysref缩放功能。读取sysref窗口位置后，应该对寄存器0x29的bit 3:0进行编程。请阅读数据表www.ti.com/.../adc12qj1600-q1.pdf中的以下段落，了解如何对sysref_sel 进行编程。
