ADC12QJ800-Q1: 急急急，这个芯片太难用了，求问寄存器配置顺序，寄存器配置表

?? ?
Prodigy 60 points
Part Number: ADC12QJ800-Q1

需求：

   器件输入时钟使用差分时钟：输入144MHz，

    使用CPLL 生成采样率720Mpsp采样信号

    JESD使用mode0，单lane速率5.76Gbps，使用8个lane，数据加扰，sysref信号2.25MHz

配置过程：

首先，根据手册9.3章节使用如下寄存器配置顺序和值，读取CPLL，SPLL未锁定，JESD  未发出同步码 
  

   图中第一列为寄存器地址，第三列为写入的寄存器值，在0x00 寄存器 写入0xB0后，读取0x270-寄存器为 0x01，然后继续写入，写入完成后没有反应

然后使用如下的寄存器配置表：

    {0x00U, 1U, 0xB0U, 0x00U},
{0x02U, 1U, 0x00U, 0x00U},
{0x10U, 1U, 0x00U, 0x00U},

{0x367U, 1U, 0x00U, 0x00U},  

第一列为地址，第三列为寄存器写入值，CPLL SPLL未锁定，没有反应，

请问有没有准确的按照顺序配置的寄存器配置表

    已给答复，您尝试以下寄存器配置：

    Address Value // Comments

    0x000     0xB0 // reset the ADC

    delay (100 mSec) // wait for 100milli second)

    0x03F     0x4A

    0x058     0x81

    0x05C     0x01

    0x03D     0x04

    0x03E     0x05

    0x05D     0x41

    0x05C     0x00

    0x057     0x81  // ONLY USE IF TRIG OUT is getting used.

    0x02B  0x15 // EN_VA11_NOISE_SUPPR

    0x0200 0x00 // Clear JESD_EN (always before CAL_EN)

    0x0061 0x00 // Clear CAL_EN (always after JESD_EN) 

    0x0201 0x00 // Set JMODE0

    0x0202 0x03 // Set KM1=3 so K=4

    0x0204 0x01 // Use SYNCSE input, offset binary data, scrambler enabled

    0x0213 0x0F // Enable overrange, set overrange holdoff to max period 4*2^7 = 512 samples

    0x0061 0x01 // Set CAL_EN (always before JESD_EN)

    0x0200 0x01 // Set JESD_EN (always after CAL_EN)

    0x006C 0x00 // Set CAL_SOFT_TRIG low to reset calibration state machine

    0x006C 0x01 // Set CAL_SOFT_TRIG high to enable calibration
