    我买了一个HMC747的D触发器的开发板,根据芯片的datasheet,它应该是边沿触发的,但是我在做测试的时候发现,它似乎是电平触发。具体内容如下:1,我输入高电平3.1V给CP,CN悬空,这个状态一直保持着,DP输入一个1MHZ的方波信号,结果QP输出1MHZ的方波信号。 2.我输入高电平3.1V给CP,输入低电平2.0V给CN,一直保持这个状态,DP输入一个1MHZ的方波信号,结果QP输出1MHZ的方波信号。 3.我输入低电平2.0V给CP,CN悬空,一直保持这个状态,DP输入一个1MHZ的方波信号…

  • HMC746;HMC747:HMC749

    1. I would like to ask the high-speed devices hmc746/747/749, how many volts do they recognize, and how many volts are considered low. In other words, how much differential voltage we should input will be regarded as high and low by these devices.
    2. In…

  • hmc747/hmc746/hmc749 single-ended interface

    How to connect unused input and output ports such as HMC747, HMC749, HMC746, etc. Is it connected in series with 50 ohms to ground? In other words, how to use a single-ended interface instead of a differential interface?

    Hello,

    I have a question regarding DC Coupling LVDS to CML, I have a non-DC balanced LVDS signal, with a low duty cycle pulse that I need to

    interface with the HMC747 flip flop (a CML part) .  The signal is currently driven by an Aeroflex/Cobham UT54LVDS031LVE…
