I would like to ask whether the HMC747 T trigger is level trigger or edge trigger.
According to the description of datashee, it should be edge trigger, but when I was doing experiments, I found that it should be in line with level trigger. When CP is continuously high and there is no level change, the level conversion of DP can be sent to QP
我想请问一下HMC747 T触发器是电平触发还是边沿触发。

Hello Rover,

Thank you for your inquiry and welcome to the community.

From my interpretation of the datasheet, you have the state of DP, which, at the rising edge of clock signal, CP, gets reflected onto QP, with a propagation delay, Td of 105 picoSeconds.
