TW3811-TB2-CR

Overview

The TW3811-TB2-CR is a receiver modem PHY chip from the Techwell SLOC solution family, developed by Intersil. It enables existing CCTV coaxial cable infrastructure to support digital IP camera functions without disrupting traditional analog services. The device allows for seamless migration from analog systems to IP security systems, supporting mixed monitoring environments where analog CVBS video and digital IP video are transmitted simultaneously over a single coaxial line.

Feature Summary

• Simultaneous transmission of analog CVBS and digital IP video over existing coaxial cables
• Enables IP camera functionality on legacy CCTV infrastructure without service disruption
• Supports hybrid monitoring systems with no-delay analog preview and network IP capabilities

Applications

• Security surveillance systems requiring coexistence of analog and IP cameras
• Upgrading existing CCTV installations to support IP features
• Hybrid monitoring solutions utilizing legacy coaxial cabling

Procurement Notes

Verify that the specific suffix TB2-CR corresponds to the intended package type and environmental rating as defined in official Intersil documentation. Confirm compatibility with the corresponding transmitter component TW3801 for complete SLOC link implementation. Ensure the procurement source provides authentic datasheets confirming the part number's electrical characteristics and pinout configuration.

Selection Notes

Select this component when integrating IP camera capabilities into facilities relying on established coaxial wiring. It is suitable for projects requiring simultaneous analog and digital video transport without rewiring. Consider the TW3811-TB2-CR alongside the TW3801 transmitter to establish a full SLOC bridge. Evaluate system requirements for maximum transmission distance and bandwidth needs against the SLOC technology specifications.
