Product details

The LMH0031VS is a deserializer and descrambler IC from National Semiconductor, designed to recover serial digital video streams that comply with SMPTE standards. It takes a serialized SMPTE bitstream and outputs parallel video data, making it a core component in professional broadcast and production video chains — cameras, routers, switchers, and monitors that handle SDI signals. The part operates from a 2.375V to 2.625V supply rail, so the board needs a regulated 2.5V supply — not a generic 3.3V or 1.8V rail. The control interface is serial, meaning setup and monitoring happen over a simple two-wire link rather than parallel address lines. Packaged in a 64-TQFP (10x10 mm) body with a 0.5 mm pitch, it mounts on the surface of a standard PCB.

Lifecycle and compliance — what to expect

One hard constraint: this part is RoHS non-compliant. It belongs in legacy builds or exempt military/industrial equipment where leaded solder is still permitted.

Sourcing and fit for your BOM

Because the LMH0031VS is active and RoHS non-compliant, it is not a part every distributor stocks on the shelf. If you are filling a BOM line for a broadcast video board that already uses this part, the active status means no scramble for last-time-buy inventory.

Frequently asked questions

What is the difference between LMH0031VS and LMH0031VE?

The LMH0031VS and LMH0031VE share the same deserializer/descrambler function and SMPTE standards support. The difference is in the package variant — the VS suffix indicates a 64-TQFP (10x10) body, while the VE suffix typically denotes a different package option (often a smaller or leadless package). Verify the package code against your board footprint before substituting.
