Product Description
The CM2030 HDMI Transmitter Port Protection and
Interface Device is specifically designed for next gener
ation HDMI Host interface protection.
An integrated package provides all ESD, slew rate lim
iting on CEC line, level shifting/isolation, overcurrent
output protection and backdrive protection for an HDMI
port in a single 38-Pin TSSOP package.
The CM2030 part is specifically designed to provide
the designer with the most reliable path to HDMI 1.3
CTS compliance.
The CM2030 also incorporates a silicon overcurrent
protection device for +5V supply voltage output to the
connector.
