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™.
