(1/2) Common Mode Filters(SMD) For DVI / HDMI Conformity to RoHS Directive ACM-D/H Series ACM2012D/H Types FEATURES • 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™. APPLICATIONS • For new HDMI™ interfaces used in digital video devices: ACM2012H is suited for use on the transmission side (Source) of digital TVs, DVD recorders and liquid crystal projectors. ACM2012D is suited for use on the receiving side (Sink). • For digital video signal interfaces DVI (UXGA) used in PCs and other devices/High-speed differential signal interfaces for USB 2.0, IEEE1394 and Serial-ATA.
