LMH0071SQX/NOPB

Serializers, Deserializers Overview

The LMH0071SQX/NOPB is a high-speed serializer/deserializer component manufactured by Texas Instruments, designed for professional video applications. It operates as a 3 Gbps SDI deserializer supporting standards including DVB-ASI, SMPTE 259M, SMPTE 292M, and SMPTE 424M. The device features a 5-bit LVDS interface and requires no external VCO or clock. It provides reclocked serial loopthrough with an integrated cable driver. Key electrical parameters include an operating supply voltage range of 2.375 V to 3.465 V (typically 3.3 V) and a power dissipation capability of 440 mW. The unit supports input/output configurations with 2 inputs and 5 outputs, housed in a 48-WQFN package.

• High-definition and standard-definition serial digital interface (SDI) receivers
• Video processing equipment requiring reclocking and loopthrough capabilities

Serializers, Deserializers Procurement Notes

Verify the specific suffix 'SQX' against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage requirements within the 2.375 V to 3.465 V range. Confirm moisture sensitivity handling procedures are followed during assembly, as indicated by manufacturer guidelines. Cross-reference pinout diagrams with PCB layout designs to ensure correct interface alignment.

Serializers, Deserializers Selection Notes

Select this component when a 3 Gbps deserialization rate is required for SMPTE and DVB-ASI standards. It is suitable for designs needing integrated loopthrough without external clocking circuitry. Consider the 48-WQFN package constraints for thermal management and board space. Verify that the LVDS interface matches the source device output specifications.

Serializers, Deserializers Part Context

The LMH0071 belongs to Texas Instruments' family of high-speed serializers and deserializers tailored for broadcast and professional video markets. It complements other components like the LMH0070 serializer by providing complementary deserialization functions. The device addresses the need for compact, low-power solutions in multi-channel video routing and processing architectures.

Serializers, Deserializers Replacement Considerations

LMH0071SQE/NOPB: Check if the 'E' suffix denotes a different package variant or temperature grade compared to 'SQX'. Verify functional equivalence regarding pinout and electrical characteristics before substitution.
