About the Simplified MFG HDSURGE

James Ralston

A little extra peace of mind

Power surges can travel between components across audio/video cables, including HDMI. This easy solution from Simplified MFG is "plug-and-play," and it prevents harmful surges from traveling across an HDMI cable. It guards against larger power surges, including ones generated by power supply failures in connected devices. Plus it wards off harmful electrostatic discharges that can sometimes happen when simply plugging in a cable between two particular components.

Product highlights:

  • protects downstream HDMI components from surges generated by source components, like a streaming media player or set-top box
  • passes 4K video
  • compatible with HDCP 2.2 copy protection
  • guards against electrostatic discharge (ESD)
  • prevents a power supply failure on one device from damaging other connected devices
  • 1-1/16"W x 7/16"H x 1-9/16"D
  • warranty: 3 years

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.
