Applications

Displays and Digital Television Product Description The CM2020 HDMI Transmitter Port Protection and Interface Device is specifically designed for next gen- eration 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 comple- ment 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.
