HDMI Receiver Port Protection and Interface Device
Features
• 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
Applications
• PC
• Consumer Electronics
• Set Top Box
• Displays and Digital Television
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.)

Note 1: Operating Characteristics are over Standard Operating Conditions unless otherwise specified.
Note 2: This parameter is guaranteed by design and verified by device characterization.
Note 3: Standard IEC 61000-4-2, CDISCHARGE=150pF, RDISCHARGE=330Ω.
Note 4: Human Body Model per MIL-STD-883, Method 3015, CDISCHARGE=100pF, RDISCHARGE=1.5kΩ
Note 5: These measurements performed with no external capacitor on TMDS_BYP.
Note 6: Intra-pair matching, each TMDS pair (i.e. D+, D-)
