Overview
Engineered for SMPTE serial digital video, the Texas Instruments LMH0384SQE/NOPB targets 3G‑SDI (2.97 Gbps), HD‑SDI, and SD‑SDI transport. The device’s adaptive equalization automatically compensates for frequency‑dependent cable loss, helping maintain compliance over a broad set of coax runs and deployment scenarios. Housed in a 16‑lead WQFN and rated for −40°C to +85°C operation, it supports space‑constrained broadcast gear and field‑deployed equipment where reliability and thermal headroom matter.
Key value points for engineering and sourcing teams:
- Standards‑anchored design: Compatibility with SMPTE 424M/292M/259M reduces integration uncertainty and accelerates compliance testing.
- Extended‑reach equalization: Enhances link robustness on long or aging coax cables (reach is implementation‑dependent; consult the datasheet for design guidelines).
- Industrial temperature rating: Suitable for studio racks, OB vans, and equipment rooms with variable ambient conditions.
- Compact package: 16‑WQFN simplifies dense layouts in routers, multiviewers, and camera back‑ends.

Standards and Compliance
The LMH0384SQE/NOPB is intended for SDI video links compliant with:
- SMPTE 424M (3G‑SDI)
- SMPTE 292M (HD‑SDI)

This alignment with SMPTE specifications helps ensure interoperability in mixed‑vendor broadcast infrastructures and reduces the risk of non‑compliant signal characteristics at key router, DA, or monitoring interfaces.
Environmental and materials compliance:
- RoHS/Environmental status: Not specified in datasheet. The “/NOPB” suffix from Texas Instruments typically denotes lead‑free; however, always confirm official RoHS/REACH status on the TI product page or compliance documents before release to manufacturing.
Applications
- Broadcast video routers and switchers
- Distribution amplifiers and equalizing stages
- Cameras and camera control units (CCUs)
- Monitors and professional displays
- Video servers, recorders, ingest, and playout systems
- Any SDI node requiring cable loss compensation ahead of reclocking or deserialization
Why this device is a good fit:
- Adaptive equalization can stabilize link performance across different cable types, lengths, and installation ages.
- Broad SDI standards support simplifies using a single equalizer across SD, HD, and 3G workflows.
- Compact WQFN package aids in miniaturized designs without compromising temperature range.
Design and Integration Notes
The following integration practices are common in SDI front ends and can help you get to first‑pass success. Always defer to the TI datasheet for device‑specific recommendations and reference schematics.
Board‑level signal integrity:
- Maintain 75‑ohm impedance for SDI paths from the connector through the equalizer I/O network.
- Keep the high‑speed path short and direct; avoid unnecessary vias and stubs.
- Provide solid return paths under SDI traces; manage reference plane transitions carefully to minimize discontinuities.
I/O conditioning:
- SDI systems commonly use AC coupling and proper termination at the receiver input. Follow TI’s recommended application circuits for coupling capacitor values and terminations.
- If your architecture includes a downstream reclocker or deserializer, place it close to the equalizer output to minimize post‑equalization trace loss.
Power and grounding:
- Decouple each power pin close to the package with low‑ESL capacitors. Provide bulk capacitance per rail as guided by the datasheet.
- Partition analog and digital grounds as recommended by TI; tie at the designated point if specified.
Thermal and mechanical:
- 16‑WQFN enables compact layouts. If the package includes an exposed thermal pad, observe the datasheet’s land pattern, via array, and solder recommendations to ensure thermal and mechanical reliability.
EMI/EMC and protection:
- Maintain clean return paths and consistent impedance to mitigate radiated and conducted emissions.
- At SDI connectors, system‑level ESD and surge protection may be required depending on the deployment environment. Select protection devices compatible with 3G‑SDI bandwidths.
Validation strategy:
- Use a PRBS source or standard SDI pattern generator and a compliant SDI analyzer or scope with an SDI compliance package to verify eye opening and jitter at 2.97 Gbps, 1.485 Gbps, and 270 Mbps as applicable.
- Validate equalizer performance with the cable types and lengths representative of your real deployment to confirm margin.
