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.
Applications
• PC and consumer electronics
• Set top box, DVD RW, PC, graphics cards
