HDMI ESD Protection without Sacrificing Performance
Adding ESD Protection to HDMI, even at 3.4GHz, Just Became Easier
The newest high-definition multimedia interface (HDMI) 1.3
standard doubles the previous HDMI 1.0 - 1.2 data rate to 3.4Gbps
per differential signal pair. This increased data rate introduces
new challenges in implementing a solid board design with low
capacitance that ensures adequate signal integrity. This is
particularly important when executing a robust electrostatic
discharge (ESD) protection solution. Adding ESD protection to
your HDMI system design can be simplified by choosing the
proper solution. Tyco Electronics' ESD and overcurrent
protection reference layout complies with the HDMI 1.3
specification at 3.4GHz, helps meet the requirements of the IEC
61000-4-2 ESD protection specification, and optimizes board
space, all of which helps minimize risk for designers. This paper
explores the requirements and pitfalls of designing ESD
protection into HDMI 1.3 systems.
