STDVE103ABTY - Adaptive TMDS/HDMI Equalizer | STMicroelectronics
部品番号: STDVE103ABTY ✗ 生産終了STDVE103ABTY 概要
An HDMI signal equalizer is a specialized interface IC that compensates for channel degradation in high-speed digital connections. In the broader product hierarchy, it belongs to interface ICs, which connect source and sink equipment while preserving signal integrity. The TMDS signaling method used by HDMI combines data and clock information into differential lanes, making equalization important when cable length, source impedance, or load capacitance exceeds the preferred operating conditions.
The verified product information identifies STDVE103ABTY as an adaptive TMDS/HDMI equalizer with I²C control. Its available supply rails are 3.3 V and 5 V, and its specified industrial temperature grade covers -40 °C to +85 °C. The 64-terminal gull-wing TQFP construction provides the lead spacing and pin count expected for a device intended to be mounted on a conventional surface-mount PCB.
The adaptive equalization architecture is significant because it allows the device to address amplitude-dependent losses encountered across different cable lengths and system layouts. I²C control provides a configuration path for system firmware or an HDMI source device, while the equalizer itself handles the analog signal-conditioning role. Exact supported data rates, equalization levels, and register details are not present in the supplied verified records and must be confirmed in the manufacturer datasheet before a new design is released.
Typical uses include HDMI source equipment, HDMI sink equipment, set-top boxes, television and monitor interfaces, and other consumer electronics that receive or transmit TMDS signals over copper wiring. The dual 3.3 V and 5 V supply information makes the device relevant to systems that contain both logic and interface voltage domains, although the exact power-rail connection requirements remain to be verified from the original documentation.
For implementation, place the equalizer close to the connector or cable interface when practical, maintain the recommended high-speed trace topology, and provide solid return paths for the differential pairs. Designers should also confirm pin assignments, bypass-capacitor values, supported HDMI configurations, and reset or control behavior against the original STMicroelectronics datasheet before layout release.
This page consolidates verified supply, package, interface, temperature, lifecycle, sourcing, and design information for STDVE103ABTY. It also distinguishes documented facts from parameters that remain unavailable, avoiding unsupported substitution, pricing, pinout, and performance claims while providing a practical basis for legacy-design review.

主な用途
STDVE103ABTY の用途: 6 件s: HDMI Television Input, HDMI Monitor Signal Conditioning, Set-Top Box HDMI Interface, HDMI Source Equipment, HDMI Sink Equipment, Professional Video and Test Equipment.
HDMI Television Input
STDVE103ABTY fits an HDMI television input because it is explicitly designed as an adaptive TMDS/HDMI equalizer and supports both 3.3 V and 5 V supply options. It can be positioned near the external HDMI connector to condition differential signals before they reach the television’s video-processing circuitry. The verified 64-pin TQFP package provides 64 terminals for the high-speed lanes, auxiliary data, control, supply, and grounding functions. Its -40 °C to +85 °C industrial range also accommodates temperature-controlled consumer and professional television environments. Designers must still confirm the supported HDMI generation, lane count, register map, and exact pin functions from the manufacturer datasheet before finalizing the television motherboard.
HDMI Monitor Signal Conditioning
In an HDMI monitor, STDVE103ABTY can be used close to the display connector to counter TMDS signal degradation caused by cable length, connectors, and PCB routing. Its adaptive equalization function is relevant because the required compensation changes with the physical channel, while its I²C interface allows a system controller to configure the device. The confirmed 3.3 V and 5 V supply options support mixed-voltage consumer electronics, and the industrial -40 °C to +85 °C range provides useful environmental margin. Before placement, engineers should verify input impedance, supported resolutions, lane mapping, and whether the equalizer belongs on the source side, sink side, or both.
Set-Top Box HDMI Interface
STDVE103ABTY is applicable to a set-top box that must deliver reliable TMDS signals over an external HDMI connection. Placing the equalizer near the connector can reduce the impact of launch and route discontinuities before the signal reaches the box’s main processor or scaler. The verified I²C control path permits firmware-based configuration, while 3.3 V and 5 V supply options align with common processor and interface voltage domains. Its 64-pin TQFP footprint requires careful high-speed layout with short differential paths and an uninterrupted reference plane. The manufacturer datasheet must be consulted for supported link rates, register defaults, power-up behavior, and input and output termination requirements.
HDMI Source Equipment
STDVE103ABTY can support HDMI source equipment when a cable or board interconnect introduces unacceptable signal degradation. The adaptive equalizer can be placed at the transmitter side of the external interface to condition the outgoing TMDS lanes, while I²C control permits configuration by the source controller. Its confirmed supply options of 3.3 V and 5 V make it suitable for systems with more than one logic voltage, subject to the original pin-level requirements. The 10 mm × 10 mm TQFP package also leaves room for conventional routed escape versus a larger fine-pitch package. Verification should cover supported HDMI standards, maximum data rate, power consumption, and whether source-side equalization is required for the target cable lengths.
HDMI Sink Equipment
STDVE103ABTY can be placed in an HDMI sink product to recover and condition TMDS data arriving over a copper cable. This application is particularly relevant when connector and PCB losses reduce signal margin before the receiver electronics. The adaptive architecture addresses different channel losses, and the I²C interface gives the host processor a configuration path for equalization and related device settings. Available supply information includes 3.3 V and 5 V, while the specified -40 °C to +85 °C range covers industrial temperature conditions. Engineers must verify receiver compatibility, lane polarity, supported resolutions, configuration registers, and whether the sink already incorporates equivalent equalization before choosing this obsolete device for a new platform.
Professional Video and Test Equipment
STDVE103ABTY can be used in professional video or test equipment that includes an HDMI interface requiring controlled signal conditioning. The industrial temperature grade supports equipment operating across -40 °C to +85 °C, and the 64-pin TQFP package provides a practical surface-mount solution for multi-layer boards. I²C control is useful in instrumentation where operating modes, diagnostic reads, or configuration sequences must be managed by a system controller. For laboratory equipment, designers should ensure that the selected equalization profile supports the intended HDMI signal rate and cable length. The supplied data does not specify jitter, gain, return loss, maximum data rate, or register functions, so these parameters require confirmation from the manufacturer datasheet.

設計ノート
Place STDVE103ABTY close to the HDMI connector or other point where channel loss is introduced. Keep TMDS differential traces short, matched, and referenced to an uninterrupted ground plane. Avoid introducing stubs, abrupt impedance changes, and right-angle routing between the connector and equalizer. Although exact trace geometry is not included in the supplied data, a controlled-impedance layout is essential because poor return paths can negate the benefit of adaptive equalization.
Separate the 3.3 V and 5 V supply domains according to the manufacturer pin assignments and decoupling recommendations. The verified records identify both supply options but do not provide capacitor values, quiescent current, or a rail-to-rail connection map. Confirm those details in the original datasheet before calculating the power budget. Place bypass capacitors at the relevant supply pins with short ground returns, and verify startup and power-supply sequencing against the system requirements.
Do not assume that any HDMI equalizer sharing a 64-pin package is a drop-in replacement. I²C addresses, register maps, equalization curves, pin multiplexing, termination, and supply sequencing can differ even when the package outline matches. The supplied cross-reference evidence contains no confirmed replacement for STDVE103ABTY. For an existing PCB, verify every pin against the original STMicroelectronics datasheet and compare the substitute’s supported data rate and channel-loss profile.
コンプライアンス情報
The supplied verified records do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable because the part is classified as a consumer or industrial interface IC rather than an automotive-qualified device.
