LMH0046MHX/NOPB

Specialized Overview

The LMH0046MHX/NOPB is a high-speed serial digital video data reclocker manufactured by Texas Instruments. Designed for HD and SD Serial Digital Interface (SDI) applications, it accepts single-ended input signals and provides dual differential outputs. The device operates within a supply voltage range of 3.3 V and supports maximum data rates up to 1.485 Gbps. It is housed in a 20-pin HTSSOP package with an operating temperature range from -40°C to +85°C.

Specialized Feature Summary

• Integrates clock and data recovery (CDR) circuitry to regenerate clean digital video signals from incoming serial streams.
• Features dual independent differential output drivers capable of driving standard 75-ohm transmission lines.
• Supports multiple serial digital video standards including HD-SDI and SD-SDI without external configuration.

Specialized Applications

• HD/SD SDI signal distribution systems
• Video monitoring and recording equipment
• Broadcast infrastructure signal regeneration

Specialized Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance status according to the manufacturer's current documentation. Confirm the package variant matches the required PCB footprint for the 20-pin HTSSOP form factor. Ensure the operating environment remains within the specified thermal limits during integration.

Specialized Selection Notes

Select this component when designing circuits requiring reliable reclocking of HD or SD serial digital video signals. It is suitable for applications needing differential output signaling to minimize noise over cable runs. Consider the 1.485 Gbps maximum data rate limit when evaluating compatibility with higher-speed video formats.

Specialized Part Context
