EMI8143MUTAG 概要
A common mode filter (CMC, also known as a common mode choke) is a passive component placed in series with a differential signal pair to attenuate common-mode noise while passing differential-mode signals. CMCs are a category within EMI/RFI filters, sitting in the broader power-management and circuit-protection taxonomy of signal-conditioning components. By integrating ESD protection into the same package, parts like the EMI8143 eliminate a separate protection diode array, simplifying layout and reducing parasitic inductance between the filter and the protection element.
The EMI8143 targets 100 mA per-line current handling and adds typically 6 ohm DCR, with a typical 15 dB common-mode attenuation specification. The integrated ESD diodes are designed to clamp fast transients on the signal lines and protect downstream HDMI transmitters/receivers. Because HDMI TMDS lines operate at up to 6 Gbps (HDMI 2.0) and the CMC must not distort the differential signal, designers should review the differential-mode insertion loss and Sdd21/Scc21 plots in the manufacturer datasheet to confirm margin at the operating data rate.
Typical applications include HDMI ports on the device side (source/sink), DisplayPort interfaces, USB 3.0 high-speed lines, Mobile High-Definition Link (MHL), and other consumer-electronics interfaces where both EMI compliance and ESD robustness are required by HDMI CTS and USB-IF compliance programs. The compact footprint also benefits portable and wearable HDMI dongles, set-top boxes, and TV main boards.
When designing with the EMI8143, place the filter as close as possible to the external HDMI connector so that the ESD diodes provide maximum protection to upstream components. Ground the TVS common pin to a low-impedance chassis or digital ground, and follow onsemi's recommended PCB layout to maintain the differential-mode signal integrity through the choke.

主な用途
EMI8143MUTAG の用途: 6 件s: HDMI 2.0 Source Port EMI Suppression, USB 3.0 High-Speed Port Filtering, DisplayPort 1.2 EMI Filtering, Set-Top Box HDMI Sink Port Protection, Mobile HDMI Dongle EMI Filtering, Industrial Camera Link Interface.
HDMI 2.0 Source Port EMI Suppression
The onsemi EMI8143MUTAG is purpose-built for HDMI 2.0 source-side EMI compliance, channeling three TMDS differential pairs (6 lines) through a single common-mode choke with integrated ESD. The 6 ohm typical DCR has negligible impact on TMDS current-mode drivers while the integrated TVS diodes protect the HDMI transmitter during hot-plug and cable-discharge events. Mounted within 0.3 inches of the HDMI connector, the part delivers 15 dB common-mode attenuation needed for FCC/CE radiated-emissions compliance above 1 GHz. Verify Sdd21 and Scc21 from the onsemi datasheet at the 6 Gbps TMDS operating rate to confirm sufficient differential signal margin.
おすすめ
USB 3.0 High-Speed Port Filtering
Although optimized for HDMI, the EMI8143MUTAG's 6-line topology maps cleanly onto USB 3.0 SuperSpeed (3 differential pairs: D+/D-, TX/RX). Each line handles up to 100 mA, well above USB signaling levels, and the 6 ohm DCR preserves signal amplitude for the 5 Gbps USB 3.0 eye diagram. The integrated ESD helps meet IEC 61000-4-2 air-discharge requirements for USB ports, which are field-serviceable connections exposed to user ESD events. Check differential return-loss (SDD11) against the USB 3.0 compliance mask before committing to PCB layout.
おすすめ
DisplayPort 1.2 EMI Filtering
DisplayPort 1.2 uses four high-speed differential lanes (8 lines) plus an auxiliary channel, making it borderline for a 3-pair filter, but DisplayPort 1.1a and reduced-lane configurations can use the EMI8143MUTAG on three of the four DP pairs plus AUX routed around the part. The integrated ESD and 15 dB common-mode rejection at baseband help pass DisplayPort compliance radiated-emissions tests. For full 4-lane DisplayPort designs, two EMI8143M parts (one for 3 lanes, one for the AUX plus lane 4) is a common pattern. Validate the Sdd21/Scc21 plots at the 2.7 Gbps / 5.4 Gbps DP rates from the onsemi datasheet.

Set-Top Box HDMI Sink Port Protection
STBs and streaming devices require HDMI sink-side protection against ESD from cable hot-plug and field service. The EMI8143MUTAG's integrated TVS plus 3-pair filtering make it a one-component solution for STB main boards, reducing BOM count and PCB area versus a discrete approach. The 15 dB attenuation across 1-3 GHz helps pass HDMI CTS radiated emissions for FCC Part 15 and EN 55022. The compact UDFN package fits inside small-form-factor STB enclosures where HDMI receptacles are densely packed with other ports. Choose the onsemi EMI8143 family when designing 4K STBs that need HDMI 2.0 throughput at 6 Gbps.
おすすめ
Mobile HDMI Dongle EMI Filtering
HDMI dongles (MHL-to-HDMI, Miracast, Chromecast-style adapters) have severe PCB area constraints. The EMI8143MUTAG's integrated CMC plus ESD in a single UDFN package lets a designer replace a CMC and a TVS array that together occupy approximately 50 mm^2, with one part that occupies a fraction of that area. The 100 mA per-line current is well above MHL drive levels, and the 6 ohm DCR adds only millivolts of IR drop. For battery-powered dongles, the low leakage of the integrated TVS minimizes quiescent current draw from the host USB-C or HDMI source.
おすすめ
Industrial Camera Link Interface
Machine-vision cameras using Camera Link or similar multi-pair LVDS interfaces benefit from the EMI8143MUTAG's 3-pair common-mode filtering on the LVDS data pairs. Industrial environments have higher ESD/EMI exposure than consumer HDMI ports, so the integrated TVS provides additional protection against discharge events that occur during cable mating in factory settings. The 6-line channel count supports the typical Camera Link configuration of 3 high-speed LVDS pairs. Verify with onsemi for the exact differential-mode insertion loss at the camera's clock frequency, and check the common-mode attenuation against your radiated-emissions budget.

設計ノート
Place the EMI8143MUTAG within 0.3 inches (8 mm) of the HDMI connector so the integrated TVS diodes shunt ESD transients before they propagate to upstream HDMI transmitters. Per onsemi's recommended layout, route the chassis/shield ground of the HDMI connector directly to the board chassis with a short, wide trace, and connect the part's ground pin to the digital ground plane with multiple vias for low-impedance ESD current return.
Verify the differential-mode insertion loss (Sdd21) at the operating data rate (e.g. 6 Gbps for HDMI 2.0) from the onsemi EMI8143 datasheet plots. Estimated: HDMI 2.0 eye diagram at 5e-10 BER requires Sdd21 above -3 dB up to 3 GHz; confirm the part's Sdd21 curve from onsemi provided at the worst-case channel. Excessive common-mode choke inductance can degrade the differential eye, so do not select a higher-attenuation HDMI CMC without validating the eye mask.
Do not substitute a CMC without integrated ESD for the EMI8143MUTAG in HDMI designs: HDMI CTS requires specific ESD voltage ratings, and a standalone CMC will not protect the HDMI transmitter during cable hot-plug or user-discharge events. Per onsemi's community Q&A on the EMI8143 family, ensure the substitute has equivalent ESD rating AND same footprint before PCB drop-in; footprint mismatch is the most common rework reason in HDMI filter redesigns.
