LMH0318RTWR

Video Processing Overview

The LMH0318RTWR is a multi-rate serial digital video data reclocker with an integrated cable driver designed for HD/SD SDI applications. It operates at speeds up to 3 Gbps, supporting SMPTE-SDI and DVB-ASI standards. The device features a reference-free clock and data recovery circuit that automatically detects input rates from 270 Mbps to 2.97 Gbps without external components. It includes a programmable equalizer to compensate for PCB loss and an integrated 2-to-1 MUX for source selection. Outputs are available in 75 Ω and 50 Ω configurations, compatible with ST 424, 344, 292, and 259 standards.

Video Processing Feature Summary

• Reference-free clock and data recovery eliminates the need for external reference clocks or loop filter components
• Integrated 2-to-1 multiplexer allows selection between two video sources
• Programmable equalizer compensates for printed circuit board signal loss to extend reach
• Non-disruptive on-chip eye monitor enables real-time measurement of serial data

Video Processing Applications

• HD/SD SDI signal reclocking and distribution
• DVB-ASI data transmission systems
• MADI audio/video routing equipment
• Video infrastructure requiring jitter elimination

Video Processing Procurement Notes

Verify the specific suffix RTWR against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the component matches the required operating temperature range and voltage levels for your design. Cross-reference the ordering part number with the latest Texas Instruments documentation to avoid discrepancies in pinout or electrical characteristics.

Video Processing Selection Notes

Select this component when designing systems requiring automatic rate detection for serial video data without external clock references. It is suitable for applications needing integrated cable driving capabilities with selectable impedance outputs. Consider its power consumption and SPI/SMBus programmability for system integration requirements.

Video Processing Part Context

This device belongs to the family of high-speed serial video reclockers manufactured by Texas Instruments. It shares functional similarities with other models in the series but is specifically optimized for 3 Gbps operation. The LMH0318 provides a solution for maintaining signal integrity in professional broadcast and video transmission environments.

Video Processing Replacement Considerations

The LMH1218 is a pin-compatible alternative offering higher speed capabilities with an integrated reclocker. Verify compatibility if upgrading to 12 Gbps applications. No other direct substitutes are confirmed in the provided documentation.
