• AD9776A输出问题

    你好

         我在使用AD9776A的时候碰到了一个问题，在我的设计中，芯片参考时钟是120Mhz，ADC时钟设置为480Mhz，VCO时钟1920M并且PLL显示是锁定状态。我使用15Mhz的正弦波和余弦波作为输入信号，我的输入数据速率120Mhz，TXENABLE信号保持高电平并且SYNC信号保持低电平，但是输出部分没有任何信号。我应该检查哪个部分？下面是我的寄存器的值。

         0000，0188，0208，0340，0400，0500，0600，0700，08EB，09CB，0A1F，0B00，0C02…

    The adapter makes the AD9776A board compatible with a standard FMC connector. We don't have any code that supports it, however.

  • Getting pixel data from the ADV7611 into a DAC

    Sirs:

    I am using an ADV7611 HDMI receiver and the output bus is connected to a ADV7125 DAC.  Unfortunately the ADV7125 will not interface with the differential IQ lines to my ADL5375 modulator.

    May I substitute an AD9785 or a AD9776A for the ADV7125…
