For Ultra High-speed Differential Signal Line
These are a series of broadband common mode filters developed for high-speed differential signal interfaces, such as DVI and HDMI?.
The cutoff frequencies in differential mode for ACM2012D and ACM2012H are 3.5GHz and 6.0GHz respectively, so they do not interfere with high-speed differential signals.
The characteristic impedance is approximated to 100Ω, conforming to the TDR standard for HDMI?.
