As shown as the top, the input common-mode voltage refers to the red or blue circle?
By the way, can the ADL5565 be configured for attenuation mode, such as -6db?
Thank you very much!
The specifications are intended for the end user who does not have access to the inside of the device . The specifications only describe the behavior of the device starting with the pins in relation to the outside world. Therefore, this range belongs to the red circle.
