使用AD9954/3/2/1的ASF调节输出波形幅值时，会影响DAC的输出位数吗？ +1
Answered

AD9954/ AD9953/AD9952/AD9951 有一个ASF(Amplitude scale factor)的14bit寄存器，可以调节输出波形的幅值，这里的幅值调节是否对AD9954内部14bitDAC的输出位数产生影响，是否还能保证在ASF修改为任意值时，DAC的输出位数都是14bit。如果修改ASF会影响DAC输出位数，那么有没有其他调节输出波形幅值的方法？

我设计的ad9910电路板，放在机箱中机箱模块5v供电，机箱收到静电时ad9910的输出会归零，通过spi读取寄存器，静电后cfr1，cfr2，cfr3这三个寄存器复位成默认值，其他step，range等寄存器保持不变。重新配置寄存器，ad9910输出恢复，我想知道静电影响了芯片的哪个位置或者引脚让cfr寄存器复位

ADL5961上电120mA，后面按照上电顺序给电，下发命令没响应。设置IGAIN后回读寄存器为全0，帮忙看看是什么原因？ 0

AD9528 同步脉冲请求问题 0
Not Answered

您好我这里在配置9528时出现了一个问题。目前配置方式是通过SPI直接写寄存器地址来完成配置出现这样一个问题同步脉冲的触发方式目前为 SPI控制我这里改写寄存器403的 bit0 是没有同步脉冲发出的？这是什么原因导致的？测试环节： 1.在初始化配置是直接将 BIT0 置1 无同步脉冲 2.先将所有寄存器进行配置（本次配置时bit0 为0）然后进行io更新。更新后，重新配置寄存器403 （本次将bit0置1）然后再次寄存器更新无同步脉冲

你好，我使用AD9910进行多片同步，采用ADCLK854进行系统时钟分发差分晶振经过ADCLK854处理的时钟信号，同时采用ADCLK854进行同步的STNC-OUT信号的分发，时钟信号正常，SYNC-OUT输出正常，频率62.5MHz左右，但是接入主片，从片，一直显示无效电平状态，那个同步引脚一直为高，请帮忙提供下技术支持。

你好，我使用AD9910进行多片同步，采用ADCLK854进行时钟分配，采用D触发器进行同步触发，系统采用40MHz晶振进行提供，通过分配器分发给9910，现在波形输出正常，有62.5MHz的同步信号输出，SYNC-CLK有250MHz的波形输出，但是一直显示未收到有效信号，同步引脚一直为高，请问我要怎么解决？

我需要对ad9528/ad9510进行初步测试，ad9528只需要测试其pll2和时钟分配功能，ad9510只需要测试其时钟分配功能，具体原理图如图假设其余元件（有源晶振和电源）工作良好，这个测试板是否有致命缺陷？因为在尝试焊接后接电，ad9528出现明显发热到40+℃的情况，我想排除原理图问题

请教AD9517-4使用问题： AD9517-4的out4~7即可以配置成lvds输出，也可以配置成cmos输出；我在使用时，可以把out4与out5配置为lvd输出，另把out6与out7配置为cmos输出吗？感谢~
