LMH0040SQ/NOPB

Serializers, Deserializers Overview

The LMH0040SQ/NOPB is a serializer and cable driver manufactured by Texas Instruments, formerly National Semiconductor. It integrates an HD, SD, and DVB-ASI SDI serializer with a high-speed LVDS cable driver in a single package. The device supports data rates up to 3 Gbps for serial digital video interfaces. It utilizes a 48-pin LLP (Leadless Plastic Chip Carrier) surface-mount package. The component operates within a commercial temperature range of -40°C to +85°C. It accepts parallel input data and converts it to a serialized LVDS output stream suitable for long-distance transmission over coaxial cables.

Serializers, Deserializers Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the suffix NOPB indicates lead-free composition and RoHS compliance. Ensure the package type matches the 48-pin LLP specification. Check for any specific tape-and-reel packaging requirements if applicable to the variant.

Serializers, Deserializers Selection Notes

Select this component when a combined serialization and line driving solution is required for SDI applications. Consider the 3 Gbps bandwidth limit for HD signals. Evaluate the 48-pin LLP footprint against available PCB space. Compare power consumption and thermal dissipation characteristics against alternative serializers or separate driver chips.

Serializers, Deserializers Part Context

This part belongs to the LMH0040 series of serializers. It is functionally equivalent to the LMH0040SQE variant, with the primary difference being the manufacturing origin transition from National Semiconductor to Texas Instruments. The device addresses the need for compact, integrated solutions in professional video infrastructure.

Serializers, Deserializers Replacement Considerations

The LMH0040SQE is a direct functional substitute. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement source confirms the same 48-pin LLP package and operating temperature range.
