Common Mode Filters(SMD)
For DVI / HDMI
ACM-D/H Series ACM2012D/H Types
FEATURES
• These are a series of broadband common mode filters devel-
oped 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 conform-
,
ing 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.
