LMH0346MHX/NOPB

Video Processing Overview

The LMH0346MHX/NOPB is a high-performance reclocker designed for serial digital interface (SDI) applications. It supports data rates up to 3 Gbps, accommodating both HD and SD video standards. The device features dual differential outputs to drive long cable runs effectively. It operates within an extended industrial temperature range of -40°C to +85°C. The component is housed in a compact 20-pin HTSSOP package. It requires a single 3.3V supply voltage for operation.

Video Processing Feature Summary

• Recovers clock signals from incoming serial digital video streams to reduce jitter and timing errors.
• Provides dual independent differential output channels for flexible signal distribution.
• Supports standard HD-SDI and SD-SDI transmission formats without external configuration.

Video Processing Applications

• Professional video broadcast infrastructure
• Digital signage signal distribution networks
• Video surveillance system processing units

Video Processing Procurement Notes

Verify the specific suffix 'MHX' indicates the tape-and-reel packaging variant distinct from the 'MH' tray version. Confirm the 'NOPB' designation ensures lead-free compliance and RoHS adherence. Check the revision letter at the end of the part number for any minor manufacturing updates. Ensure the operating environment stays within the specified -40°C to +85°C thermal limits for reliable performance.

Video Processing Selection Notes

Select this component when dual-channel output capability is required for SDI signal regeneration. It is suitable for designs needing low-jitter recovery in professional video environments. Consider the HTSSOP package size constraints during PCB layout planning. Verify that the 3.3V power supply rail meets the current requirements for the reclocking circuitry.

Video Processing Part Context

This device belongs to the LMH0346 series of video interface ICs from Texas Instruments. It serves as a critical link in maintaining signal integrity across long coaxial cable runs. The series is widely used in broadcast equipment where precise timing recovery is essential. It complements other video drivers and receivers in complete transmission chains.

Video Processing Replacement Considerations

The LMH0346MH/NOPB is a direct pin-compatible alternative differing only in packaging format. Ensure the selected substitute maintains the same 3 Gbps speed rating and dual output architecture. Verify thermal performance matches the original specifications for the intended application.
