TW2984-NA2-CR

Overview

The TW2984-NA2-CR is a video integrated circuit manufactured by Renesas Electronics Corporation, formerly Intersil. It functions as a four-channel wide D1 (960H) and D1 video/audio coder designed for surveillance applications. The device supports multiple input formats including composite video and S-Video, encoding them into MPEG-2 or H.264 streams. Key electrical parameters include a supply voltage range of 3.3V and 1.8V for core logic, operating temperatures from -40°C to +85°C, and a package type of 64-pin TQFP. It integrates on-chip analog-to-digital converters and digital signal processing capabilities for real-time encoding.

Feature Summary

• Four-channel simultaneous video and audio encoding capability
• Support for Wide D1 (960H) and standard D1 resolution inputs
• Integrated MPEG-2 and H.264 compression engines
• On-chip ADCs eliminating external digitization requirements

Applications

• Digital video surveillance systems
• Network video recorders (NVR)
• Multipoint video conferencing units
• Professional broadcast monitoring equipment

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance documentation matches the specific manufacturing lot. Check for moisture sensitivity level handling requirements during storage and assembly. Validate that the NA2 suffix corresponds to the required temperature grade and package variant for your design.

Selection Notes

Select this component when multi-channel D1 encoding is required within a single IC footprint. Ensure system power supplies match the 3.3V and 1.8V rails specified in the datasheet. Consider thermal dissipation requirements for the TQFP package in enclosed enclosures. Verify software compatibility with existing firmware architectures if using proprietary encoding profiles.

Part Context

This part belongs to the TW2984 series of video coders from Renesas/Intersil. It represents a legacy solution for high-channel-count surveillance before the widespread adoption of lower-power, higher-resolution SoCs. The series was widely used in early HD DVR systems. Current production has ceased, making it a discontinued item for new designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult Renesas for current generation alternatives such as the TW28xx series or newer video processing SoCs that offer similar channel counts and encoding standards.
