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.)
