LMH1297RTVR

Video Processing Overview

The LMH1297RTVR is a Texas Instruments video IC featuring 12G UHD-SDI bidirectional I/O with an integrated reclocker. It operates on a single 2.5 V supply and supports data rates from 125 Mbps to 11.88 Gbps. The device includes adaptive cable equalization, clock recovery, and echo loss compensation. It is housed in a 32-WQFN package and functions within a temperature range of -40°C to +85°C.

Video Processing Feature Summary

• Integrates adaptive cable equalizer and clock recovery for signal regeneration
• Supports bidirectional I/O for 12G UHD-SDI applications
• Includes internal echo loss compensation network
• Features programmable CDR loop bandwidth settings

Video Processing Applications

• Long-distance transmission over 75Ω coaxial cables
• 4K/8K video signal distribution systems
• Professional broadcast equipment requiring signal retiming
• System-level diagnostic implementations using eye monitor

Video Processing Procurement Notes

Verify the specific suffix RTVR against official datasheets to confirm the reel packaging configuration. Ensure the component meets RoHS compliance requirements for your region. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the WQFN-32 package dimensions match your PCB footprint design constraints before finalizing procurement orders.

Video Processing Selection Notes

Select this component when bidirectional I/O capability is required alongside signal retiming. It serves as a pin-compatible alternative to the LMH1229 for system redundancy. Consider its integrated features if board space is limited compared to discrete solutions. Verify compatibility with SMPTE standards relevant to your specific video resolution and frame rate requirements.

Video Processing Part Context

This device belongs to the LMH12x9 series of 12G SDI cable equalizers. It shares architectural similarities with the LMH1228 and LMH1208 but adds bidirectional functionality. The series targets professional video markets needing high-speed signal integrity over long cable runs without external retimers.

Video Processing Replacement Considerations

LMH1229 is a pin-compatible cable equalizer within the same family. LMH1228 offers dual output driver capabilities with similar form factors. Verify functional equivalence regarding bidirectional support when substituting.
