HDMI v2.1 EMI Filters
The ACTIV HDMI™ electromagnetic interference (EMI) Filter is the most advanced and effective EMI filter for HDMI available on the market. The filter is designed to pass audio, video, display data, control, power and signaling between an HDMI source and compatible device while blocking external interference. Utilizing proprietary Digital Signal Processing (DSP) techniques, the filter passes HDMI Ethernet and four balanced, differential signaling data pairs at a combined data rate of up to 48 Gbps in support of the HDMI v2.1 standard while providing greater than 80dB of insertion loss from 500MHz to beyond 18GHz. The filter is also backwards compatible with HDMI versions 2.0 and 1.4
Military grade passive filtering technology ensures that audio, video and data signals traverse the filter in complete and absolute isolation from each other and the outside world. Signal lines are balanced perfectly throughout the multilayered cards to avoid disturbing the fast rise times required by digital square wave signals. The result is a pristine digital output far surpassing the filtering capabilities of any other EMI filters.
Each ACTIV HDMI™ EMI Filter is constructed with the highest quality electrical components, starting with a super accurate, ultra stable high speed crystal clock which drives the specially developed DSP circuitry and HDMI chipset. To protect against unanticipated voltage and/or current surges, the filter incorporates ESD and transient voltage suppressors, inrush current limiters, and gas discharge tubes. ACTIV HDMI™ EMI Filters are mounted in a rugged protective housing machined from solid aluminum stock. The housing not only provides physical protection to the filter components, but is also an integral contributor to the filter's effectiveness. The unique structure of the housing effectively disrupts undesirable emissions from propagating through the filter while simultaneously providing low impedance pathways for interference to be directed out of the filter.
Features:
- Proprietary DSP technology provides unmatched EMI filtering
- Military grade passive filtering techniques maintain clean and sharp signals
- Highest grade electrical components deliver long service life
