LMH0046MHX

Specialized Overview

The LMH0046MHX is a high-performance HD/SD SDI reclocker manufactured by Texas Instruments, designed for professional video applications. It operates on a single 3.3V supply and supports data rates up to 1485 Mbps, covering standard definition (SD) and high definition (HD) serial digital interfaces. The device features dual differential outputs to drive long cable runs effectively. It is housed in a 20-pin HTSSOP package with dimensions of 6.5 mm length. The component functions within an operating temperature range of -40°C to +85°C and includes ESD protection rated at 7 kV HBM.

Specialized Feature Summary

• Provides clock recovery and signal retiming for serial digital video streams
• Generates two independent differential output pairs from a single input
• Supports both SD and HD serial digital interface standards

Specialized Applications

• Professional video distribution systems requiring signal regeneration
• Broadcast equipment utilizing SDI interconnects
• Video monitoring stations needing signal integrity restoration

Specialized Procurement Notes

Verify the specific ordering suffix to ensure compatibility with RoHS directives and lead-free requirements. Confirm that the HTSSOP-20 package variant matches the target PCB footprint. Check for any specific environmental compliance certifications required by the final assembly process before procurement.

Specialized Selection Notes

Select this component when dual differential outputs are necessary from a single SDI source. Ensure the design accommodates the 3.3V supply voltage constraint. Verify that the 1485 Mbps maximum data rate meets the highest resolution requirements of the intended video application.

Specialized Part Context

This part belongs to the LMH0046 family of video ICs. Variants such as LMH0046MH-NOPB and LMH0046MH/NOPB share similar functional descriptions but may differ in packaging or compliance status. The MHX suffix typically indicates a tape-and-reel packaging configuration suitable for automated assembly processes.

Specialized Replacement Considerations

Direct substitutes include LMH0046MH-NOPB, LMH0046MHX-NOPB, LMH0046MH/NOPB, and LMH0046MHX/NOPB. These parts share identical functional descriptions and pinouts. Verify package compatibility and environmental compliance differences before substitution.
