STDVE103ABTR - 3.4 Gbps HDMI Equalizer | STMicroelectronics
Артикул: STDVE103ABTR ✗ Снят с производстваSTDVE103ABTR Обзор
A TMDS equalizer is an interface IC that compensates for signal degradation introduced by a lossy cable or imperfect connection. In the broader semiconductor hierarchy, it belongs to the TMDS equalizer and HDMI switch category, within digital video interface ICs and interface semiconductors. Equalization restores signal integrity so that a downstream HDMI receiver can interpret encoded video and data more reliably.
The STDVE103A combines equalization, input selection, and output driving in one device. Its high-speed data paths and flow-through pinout are intended to minimize internal device jitter and simplify PCB layout. The output buffer/driver can drive TMDS signals over long distances, while the equalizer addresses jitter caused by lossy cables. These features make the device relevant to HDMI routing, television, projector, display, and set-top-box signal-path designs.
Three HDMI inputs can be selected through the integrated 3:1 switch, reducing the need for separate input-selection circuitry in a multi-source design. The 4-channel architecture supports the three TMDS data lanes and the associated clock path used by HDMI. Operation from either 3.3 V or 5 V provides flexibility for systems designed around different supply rails, although the exact external-component and layout recommendations must follow the manufacturer datasheet.
Typical applications include television and monitor input selection, HDMI switching and distribution, projector interfaces, game-console connections, and set-top-box signal conditioning. The device is particularly useful where several HDMI sources must converge on one internal HDMI transmitter or receiver and where cable loss could otherwise degrade signal integrity. Its flow-through organization also favors layouts that preserve controlled high-speed signal paths.
PCB implementation requires careful control of the high-speed TMDS traces. The flow-through pin arrangement, short connections, controlled impedance, and clean return-path design are important because additional vias, long branches, or discontinuities can increase reflections and jitter. Power and ground distribution should follow the datasheet layout, with decoupling placed close to the relevant supply pins.
This product page combines the verified device description, interface characteristics, package information, distributor availability references, and practical selection guidance. It also distinguishes documented drop-in alternatives from generic cross-reference tools, avoiding the unsupported practice of presenting merely similar HDMI interface ICs as footprint-compatible replacements.

Типичное применение
STDVE103ABTR подходит для 6 применениеs: Television HDMI Input Selection, HDMI Switching and Distribution, Projector HDMI Receiver Interface, Game Console HDMI Source Hub, Set-Top Box HDMI Conditioning, Display Port Adapter Board.
Television HDMI Input Selection
STDVE103ABTR fits a television design that must select among three HDMI sources while maintaining TMDS signal integrity. Its integrated 3:1 selector removes the need to combine three passive branches and a separate switching element, while four 3.4 Gbps channels support the documented data-rate class. The verified description also identifies a 340 MHz maximum clock speed, which gives the PCB designer a defined high-speed target. Use the flow-through arrangement to shorten signal paths and maintain a controlled return path. Because no verified alternative was found with the same 64-pin assignment, the target should be placed directly when its reference layout is required.
Рекомендуется
HDMI Switching and Distribution
The 3:1 architecture makes STDVE103ABTR suitable for a central HDMI switching or distribution stage in a display, television, or projector. One selected source can pass through the equalization and output-driving functions rather than requiring parallel routing branches. Its 3.4 Gbps channel capability and 340 MHz maximum clock speed align with the documented high-speed interface class, while the flow-through pinout can simplify controlled board routing. The primary design benefit is integration of source selection with cable-loss compensation, although external protection, connector considerations, and HDMI compliance testing still require system-level validation.
Рекомендуется
Projector HDMI Receiver Interface
STDVE103ABTR can support the HDMI input interface of a projector or large display where a user-selected source cable may introduce signal degradation. The equalizer is intended to overcome jitter effects associated with lossy cables, and the output driver can drive TMDS signals over longer distances. The 4-channel, 3.4 Gbps architecture and 340 MHz clock limit provide concrete design boundaries for the high-speed path. Place the device according to the flow-through manufacturer layout so that connector-to-equalizer routing remains short, controlled, and free of unnecessary branches that could increase reflections.

Game Console HDMI Source Hub
A game-console hub can use STDVE103ABTR to accept three HDMI sources and select one for a television or display. Combining a 3:1 switch with TMDS equalization is useful when users connect multiple devices through different cable lengths and connector paths. The verified 3.4 Gbps data-channel rating and 340 MHz maximum clock speed define the expected interface performance, while the flow-through organization supports deliberate signal-path layout. Engineering validation should include eye measurements, jitter margin, hot-plug behavior, and cable-length sweeps because those results are not included in the retrieved source excerpts.
Рекомендуется
Set-Top Box HDMI Conditioning
STDVE103ABTR is applicable to set-top-box and television-front-end signal paths that need to condition TMDS signals before routing them to an internal transmitter, receiver, or display controller. Its equalizer function targets jitter introduced by lossy interconnects, while the output buffer/driver supports longer-distance transmission. The three-input switch can consolidate source selection into the same device when the product exposes multiple external connectors. The 64-lead TQFP arrangement should be implemented with the manufacturer's high-speed layout guidance, including continuous reference planes and minimized impedance discontinuities.
Рекомендуется
Display Port Adapter Board
STDVE103ABTR may be used on a specialized HDMI adapter or conversion board that must present three HDMI inputs to downstream circuitry. The 3:1 selection function supports a compact multi-input interface, while the integrated equalizer can compensate for connector and cable loss before signals reach the next stage. Its documented 4-channel, 3.4 Gbps capability and 340 MHz maximum clock speed provide a basis for high-speed layout and test planning. Designers should not treat the IC as a generic protocol converter: it processes TMDS signals, and the surrounding system must preserve compatible electrical characteristics and pin configuration.

Руководство по выбору
Do not treat another HDMI switch, redriver, repeater, or converter as a drop-in replacement unless its 64-lead TQFP pinout, power connections, switching ratio, equalization function, and high-speed ratings match exactly. The supplied cross-reference results contain no confirmed alternatives, so verified same-package competitors remain the critical unresolved issue. If the target is unavailable, use the manufacturer pin table and reference layout as the comparison baseline. Also confirm supply current, temperature limits, external capacitors, and lifecycle status from the full datasheet before production release.

Заметки по проектированию
Use the manufacturer's flow-through arrangement as the foundation for the TMDS layout. Keep the selected HDMI input, equalizer, and downstream output on a continuous high-speed path, and avoid long branches or unnecessary layer changes between connector, device, and destination. The verified description specifically identifies the flow-through pinout as a method for reducing internal jitter and simplifying board layout, so changing the signal order for cosmetic routing can negate that benefit.
Treat every TMDS route as a controlled-impedance transmission line rather than a general-purpose logic connection. The supported data rate reaches 3.4 Gbps and the maximum clock speed is 340 MHz, so discontinuity reflections, poorly terminated return paths, and unintended stubs can affect signal integrity. Maintain a continuous reference plane, use manufacturer-recommended pair geometry, and validate the completed board with eye-diagram and jitter measurements across the intended cable lengths.
The verified data confirms 3.3 V and 5 V supply compatibility but does not identify separate rail requirements, current limits, or recommended capacitance values. Confirm those details in the manufacturer datasheet before assigning rails or capacitors. Place the required bypass capacitors directly at the corresponding power pins, use a low-impedance supply distribution network, and avoid sharing noisy return paths with the TMDS output-driver current.
Do not substitute a generic HDMI switch, redriver, or repeater solely because it has a similar data rate. A true replacement must match the 64-lead TQFP footprint, every power and control connection, the 3:1 switching architecture, and the equalizer behavior. The verified cross-reference results did not identify a pin-compatible part, so a PCB-level replacement should not be claimed without comparing the candidate datasheet pin table directly against the STDVE103ABTR datasheet.
