It accepts a serialized SMPTE data stream and outputs a parallel video bus, handling the descrambling per the standard. The part targets broadcast infrastructure, production switchers, and video routers where signal integrity through a coaxial or fiber link must be restored to a clean parallel interface. ## 2.375 V to 2.625 V supply — tight rail, clean decoupling needed The supply range is a narrow 2.375 V to 2.625 V, which means the board designer cannot share a generic 2.5 V or 3.3 V rail without a local regulator. A dedicated low-noise LDO feeding this rail is the usual approach, with bulk and high-frequency decoupling right at the 64-TQFP pins. The narrow tolerance also means the regulator's load regulation matters — a 50 mV drop under transient load could push the rail below the minimum. ## 64-TQFP package — layout and rework notes The LMH0031VS-TI comes in a 64-TQFP (10x10 mm) package with a 0.5 mm pitch. That pitch is fine for a standard reflow profile, but the tight pad spacing means the solder-paste stencil aperture needs a 1:1 pad opening — no oversized apertures that risk bridging on the serial data input pins. For rework, a hot-air nozzle sized for a 14x14 mm body works; pre-bake at 125 °C for 24 hours if the parts have been out of the moisture-barrier bag past the floor life (MSL 3 assumed for TQFP). ## RoHS non-compliant — plan for it If your bill of materials requires full RoHS conformance for EU or other regulated markets, the LMH0031VS-TI cannot be used without an exemption. The lead-bearing finish is typical for legacy broadcast equipment that still specifies tin-lead solder for field reliability. For new designs that must be RoHS, the LMH0031VSE/TI variant (if available) should be evaluated, though the evidence does not confirm it as a drop-in substitute — verify the suffix differences against the datasheet.","metaTitle":"TI LMH0031VS-TI SMPTE Deserializer/Descrambler, 64-TQFP","metaDescription":"TI LMH0031VS-TI SMPTE deserializer/descrambler for professional video. 2.375V–2.625V supply, 64-TQFP.
