Features

HDMI Surge Protector: Just by making an HDMI connection, it is possible to have an electrical discharge. The HDSURGE by Simplified MFG is an in-line HDMI surge protection device that eliminate phase shift issues, while also providing excellent ground isolation to protect your HDMI connected equipment from electrical discharge surges. Because of the potential differences between system devices (Sources, Switchers, Receivers, Displays, etc. ) connecting two devices via an HDMI cable can cause an electrical discharge too quickly, causing a spark phenomenon. The HDSURGE protects your equipment from "human-caused" discharge, as well as protecting against larger electrical discharges that may be passed from a sources, switchers, receivers, and displays.

Note: The HDSURGE is compatible with 4K/2K video, HDCP 2.2, HDMI 1.4, and HDMI 1.3.

ESD Protection: The HDSURGE is a single-chip integrated ESD (Electrostatic Discharge) protection solution for HDMI 1.4 or HDMI 1.3 interface. This device offers 13 channels of ESD clamp circuits with flow-through pin mapping that matches HDMI connector high-speed lines. While providing ESD protection, it adds little to no additional distortion to the high-speed differential signals. The monolithic integrated circuit technology ensures that there is excellent matching between the two-signal pair of the differential line (<0.05pF differential matching between TMDS lines). This is an advantage over discrete ESD clamp solutions where variations between two different ESD clamps may significantly degrade the differential signal quality.

5V Sharing Protection:The HDSURGE also incorporates an on-chip current limited load switch that is compliant with HDMI 5V out electrical specifications. The short circuit protection at 5V_Out ensures that the device is not damaged in case there is accidental short to ground (GND). The load switch also incorporates reverse current blocking feature which ensures that the HDMI driver side is not erroneously turned on when two HDMI drivers are connected. This feature prevents 5V "sharing" which is common in many HDMI devices.  If there is a power supply failure on one device, the other HDMI devices in the circuit can be damaged as the device with the power supply failure will try to draw current from other devices possibly damaging them. The reverse current blocking feature prevents this from happening.
