| CM2020 HDMI Transmitter Port Protection and Interface Device Features * * * * * * 0.05pF matching capacitance between the TMDS intra-pair Overcurrent output protection Level shifting circuitry, including 8kV ESD protection on all TMDS lines Matched 0.5mm trace spacing (TSSOP) Simplified layout for HDMI connectors Backdrive protection Product Description The CM2020 HDMI Transmitter Port Protection and Interface Device is specifically designed for next generation HDMI Host interface protection. An integrated package provides all ESD, level shift, overcurrent output protection and backdrive protection for an HDMI port in a single 38-Pin TSSOP package. The CM2020 part is specifically designed to complement the CM2021 protection part in HDMI receivers (Displays, CE devices, etc.) The CM2020 also incorporates a silicon overcurrent protection device for +5V supply voltage output to the connector.
