hello
I encountered a problem when I used the AD9776A. In my design, the reference clock was 120Mhz, the ADC clock was 480Mhz, the VCO clock was 1920M and the PLL display was locked. I use 15Mhz sine wave and cosine wave as input signal, my input data…
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…
后来调试中基本没有发现寄存器设置问题,请问这种现象正常吗?,有没有窍门
The adapter makes the AD9776A board compatible with a standard FMC connector. We don't have any code that supports it, however.
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…
Hi
Since expose paddle was mention here. We have had a lots on enquiry regarding this, not just specifically on the AD8045.
Regarding ... how (best) in connecting the Expose paddle... “in General”. The Expose Paddle otherwise, sometime Also Known As…
