•
•
•
•
0.05pF matching capacitance between the TMDS
intra-pair
Level shifting circuitry, including
±8kV
ESD protec-
tion on all TMDS lines
Matched 0.5mm trace spacing (TSSOP)
Simplified layout for HDMI connectors
Backdrive protection
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.)
