0.05pF matching capacitance between the TMDS intra-pair Level shifting circuitry, including ±8kV ESD protec- tion on all TMDS lines Matched 0.5mm trace spacing (TSSOP) Simplified layout for HDMI connectors Backdrive protection

Applications

Displays and Digital Television Product Description The CM2021 HDMI Receiver Port Protection and Inter- face Device is specifically designed for next generation HDMI Host interface protection. An integrated package provides all ESD, level shift and backdrive protection for an HDMI port in a single 38- Pin TSSOP package. The CM2021 part is specifically designed to comple- ment the CM2020 protection part in HDMI receivers (Displays, CE devices, etc.) Electrical Schematic TMDS_CK+ TMDS_GND TMDS_CK- TMDS_D2+ TMDS_GND TMDS_D2- TMDS_D1+ TMDS_GND TMDS_D1- TMDS_D0+ TMDS_GND TMDS_D0- TMDS_BYP CE_REMOTE_OUT CE_REMOTE_IN DDC_CLK_OUT DDC_CLK_IN DDC_DAT_OUT DDC_DAT_IN HOTPLUG_DET_OUT HOTPLUG_DET_IN 3.3V SUPPLY TMDS_BYP 3.3V SUPPLY TMDS_BYP 3.3V SUPPLY TMDS_BYP 3.3V SUPPLY TMDS_BYP 5V_SUPPLY
