STDVE001AQTR - 3.4 Gbps Adaptive HDMI Equalizer | STMicroelectronics
料号： STDVE001AQTR ✗ 停产STDVE001AQTR 概述
An HDMI signal equalizer is an interface IC that compensates for attenuation and distortion introduced by connectors, cables, and printed-circuit-board routing. Its role in the hierarchy is TMDS signal conditioner -> HDMI interface equalizer -> video interface IC -> consumer and industrial semiconductor. Equalization restores predictable differential signaling behavior while maintaining compatibility with transition-minimized differential signaling on input and output channels.
The STDVE001AQTR supports data rates up to 3.4 Gbps and a maximum clock speed of 340 MHz. Adaptive equalization allows the device to adjust its correction to the channel conditions. The single-signal architecture is intended for HDMI links where one channel requires conditioning. I2C control provides a means for system-level configuration and monitoring, while the 3.135 V to 3.465 V operating range ties the device closely to a regulated 3.3 V rail.
The part is listed as obsolete by distributor product data, which is important for long-term sourcing and PCB redesign planning. Its 48-VFQQN surface-mount package supports compact consumer-electronics and industrial interface layouts, but the exposed-pad construction requires careful thermal-via and copper-pour design. Because no verified unit price was supplied, the commercial tier values below are placeholders that require quotation rather than an orderable price.
Typical uses include HDMI source and sink equipment, display adapters, set-top boxes, projectors, and AV distribution hardware. The design trade-off is that the obsolete lifecycle status restricts availability, while the narrow 3.3 V supply requirement simplifies rail design but prevents direct operation from unregulated 5 V systems. Designers should verify pin compatibility and signal-integrity performance against the original system requirements before using any substitute.
This page consolidates verified distributor specifications, lifecycle information, sourcing constraints, and practical interface-design guidance that are not presented as a single set in the original component listing.

典型应用
STDVE001AQTR 适用于 6 应用s: Legacy HDMI Source Equipment, HDMI Display Adapters, Set-Top Box and Projector Inputs, AV Distribution and Extender Equipment, Digital Video Test and Measurement, Industrial Video Control Panels.
Legacy HDMI Source Equipment
The STDVE001AQTR fits legacy HDMI v1.3 source equipment where a conditioned 340 MHz clock and 3.4 Gbps data rate are required. Its single adaptive TMDS equalizer channel compensates for signal degradation introduced by cable runs, connectors, or imperfect PCB routing. The part operates from a regulated 3.3 V rail within its 3.135 V to 3.465 V specification, so the host design must provide clean, low-noise supply decoupling. Because the component is obsolete, it is most appropriate for repairing or reproducing an existing design rather than supporting new production volumes. Digital and analog ground partitioning, short TMDS traces, and controlled differential impedance remain essential for predictable link behavior.
HDMI Display Adapters
The STDVE001AQTR can be used in legacy HDMI display adapters that need adaptive compensation between source and connector. Its support for HDMI v1.3, TMDS signaling, and I2C configuration suits adapters that must translate or retime an existing link rather than originate modern high-bandwidth video. The 48-VFQQN 7 x 7 mm package permits compact adapter layouts, while the narrow 3.3 V supply range requires local regulation and close bypass capacitance. Board designers should keep TMDS pairs matched and avoid stubs between the equalizer and connector. Since the equalizer is obsolete, an adapter built today should include a documented alternate sourcing plan or use a currently supported interface controller.
Set-Top Box and Projector Inputs
Within an existing set-top box or projector architecture, the STDVE001AQTR is applicable when an HDMI v1.3 receiver path includes connector loss or long board-level routing. The adaptive equalizer provides a single correction stage for one TMDS signal and operates from 3.3 V with I2C control for system configuration. Its 340 MHz maximum clock capability aligns with the supported HDMI v1.3 use case. Placement should be near the damaged channel or connector transition rather than at an arbitrary location in the signal path. Thermal design remains relevant despite the modest signal role because the VFQPN exposed pad must be connected according to the land pattern. Obsolete lifecycle status limits this role to legacy repairs and qualified remanufacturing.
AV Distribution and Extender Equipment
The STDVE001AQTR may be used in legacy AV distribution or extender hardware where one TMDS link loses margin through cable, connector, or PCB transitions. Adaptive correction at up to 3.4 Gbps can restore signal integrity in established HDMI v1.3 systems. The device requires a narrow 3.135 V to 3.465 V supply range, which simplifies rail definition but places a meaningful restriction on systems powered directly from 5 V. I2C access permits configuration within a larger control scheme. Signal-integrity validation should compare eye margin before and after the equalizer under the intended cable length. Because the device is obsolete, production use requires an obsolescence plan and secured original inventory.
Digital Video Test and Measurement
The STDVE001AQTR can serve as the conditioning element in legacy digital-video test equipment intended to exercise HDMI v1.3 TMDS behavior. Its maximum 340 MHz clock rate and adaptive equalization make it suitable for reproducing historical link impairments in a controlled test setup. I2C control allows instrumentation software to observe or configure the device when the surrounding platform supports the same interface. The part should be evaluated only against its verified 3.4 Gbps capability; newer HDMI link rates are outside the supplied data. Prototype boards also need attention to the 48-VFQQN exposed pad and to differential trace geometry. Obsolete status favors repair and laboratory duplication over new test-platform development.
Industrial Video Control Panels
The STDVE001AQTR is applicable to legacy industrial video-control panels that receive an existing HDMI v1.3 signal across an internal cable assembly or a moderately long PCB route. The single-channel adaptive equalizer provides compensation without introducing a switching converter into the interface path. Its I2C control and 3.3 V operating range suit established control-board architectures, and the compact 7 x 7 mm VFQFN preserves routing space around dense video connectors. Industrial users should still verify temperature availability because the verified listing reports -40 C to +85 C operation while also marking the product obsolete. Spare-part strategy and traceability should be agreed before deployment in a system expected to remain in service.

关键差异点
- Documented legacy HDMI v1.3 equalization capability （对比 MAX14502AETL+T)
- Narrow regulated 3.3 V operating range （对比 MAX14502AETL+T)
- Single adaptive signal-conditioning channel （对比 MAX14502AETL+T)
设计说明
Place the STDVE001AQTR close to the HDMI connector or the point where the TMDS pair has accumulated the most loss. Route the relevant differential pair as a controlled-impedance pair with matched length through the equalizer rather than creating stubs. The verified material does not supply a trace-impedance value, so the value must be taken from the original product's PCB constraints and signal-integrity simulations rather than assumed.
Use a regulated 3.3 V rail that remains inside the verified 3.135 V to 3.465 V operating range under load and temperature. Place local high-frequency bypass capacitance directly at the supply pins and keep the return path continuous beneath the package. Exact capacitor values are marked as unavailable because no verified application circuit or recommended capacitance was included in the supplied records.
Treat the exposed pad as a thermal and layout structure, not as an optional mechanical feature. Follow the manufacturer land pattern for exposed-pad vias and connect the pad to a continuous ground or power plane according to the datasheet. The available records do not state theta_JA, pad dimensions, or via recommendations, so those values must be obtained from the original 49-page datasheet before layout release.
Do not treat every HDMI-interface IC as a substitute for this device. The supplied cross-reference information explicitly states that the MAX14502AETL+T is not a direct pin-to-pin or functionally equivalent replacement and that its 2.7 V to 5.5 V supply range differs from this device's 3.135 V to 3.465 V range. Board changes, firmware control, and signal validation are mandatory for any redesign.
合规信息
The supplied verified records state that the package uses matte tin terminal finish but do not explicitly document RoHS, REACH, AEC-Q100, halogen-free, or conflict-minerals status. These fields therefore remain unknown rather than inferred.
