HDMI Protection
Highlights:
- High speed media, data transfer interface with 6 control lines & 8 data lines
- Operating voltage:
- For each data and control line, 3.3V and 5V respectively
- This requires a protection diode with breakdown voltage of at least 3.6V, 5.5V respectively
- Operating frequency:
- HDMI 2.1 – 20Gbps
- HDMI 2.0 – 6Gbps,
- HDMI 1.4/1.3 -3.4Gbps
- These high speed transfer requires lower capacitance of < 1pF
