HDMI? Port
HDMI 1.3 - ESD & Overcurrent Protection
Solution Products
Objective
HDMI 1.3 interfaces are 3.3 V differential
digital signals with single-link bandwidths
up to 340 MHz (10.2 Gbit/s). As usage of
HDMI ports increases, HDMI ports face a
growing threat of ESD damage.
Solution
2 TVS Diode Arrays: CDDFN10-0524P
1 TVS Diode Array: CDSOT236-0504LC
1 Multifuse? PPTC: MF-FSMF020X-2
Compliance
IEC 61000-4-2 Level 4 (8 kV / 15 kV)
Alternate Recommendations
Other PortNote? Solutions:
? HDMI: HDMI 1.4 - ESD & Overcurrent Protection
Benefit
This solution provides IEC 61000 Level 4 ESD
protection without impairing the HDMI signal.
