TW6869-TA1-CRH

Overview

The TW6869-TA1-CRH is an integrated video decoder IC designed for multi-channel video and audio capture applications. It supports eight channels of video decoding via a PCI Express x1 interface, making it suitable for PC-based DVR systems. The device operates with dual power supplies of 1.2 V and 3.3 V, drawing a typical operating current of 190 mA. It is housed in a 144-pin TQFP package (20x20 mm) and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrates eight-channel video decoding capabilities with embedded encoding functionality
• Connects to host systems via a high-speed PCI Express x1 media bridge interface
• Supports simultaneous multi-channel video and audio capture for surveillance applications

Applications

• PC-based Digital Video Recorder (DVR) systems
• Video analytics platforms requiring multi-channel input
• Surveillance recording solutions

Procurement Notes

This component is officially classified as obsolete by the manufacturer. Production has ceased, and the part is no longer available through standard new production channels. Procurement efforts should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the specific suffix and condition of available units, as availability is limited and subject to existing inventory constraints.

Selection Notes

Engineers selecting this component should note its legacy status and limited future supply chain support. The design requires compatibility with PCI Express x1 interfaces and appropriate voltage regulation for 1.2 V and 3.3 V domains. Due to the obsolescence, alternative solutions with modern interface standards or longer lifecycle commitments may be necessary for new product developments. Existing designs utilizing this part should plan for migration strategies.

Part Context

The TW6869 series represents a family of highly integrated video processing solutions from Renesas Electronics. This specific model combines video decoding and encoding functions into a single chip, reducing board space and complexity compared to discrete solutions. It was widely used in mid-generation DVR architectures before being superseded by newer generations with enhanced codec support and interface options.

Replacement Considerations

No public confirmed substitute part numbers are documented for this specific obsolete component.
