EL4581CS-T7

Overview

The EL4581CS-T7 is a video sync separator integrated circuit manufactured by Renesas Electronics Corporation. It supports NTSC, PAL, and SECAM standards for professional video applications. The device operates on a single 5V supply voltage and is housed in an 8-SOIC surface-mount package with a width of 3.90mm. It functions as a dedicated sync separator IC designed to extract synchronization signals from composite video inputs.

Feature Summary

• Extracts synchronization signals from composite video formats including NTSC, PAL, and SECAM
• Operates on a single 5V power supply
• Designed for professional video signal processing applications

Applications

• Professional video equipment
• Video signal processing systems
• Composite video input stages

Procurement Notes

Verify component authenticity and datasheet alignment due to end-of-life status. Confirm RoHS compliance requirements as the base EL4581CS is noted as non-compliant. Check moisture sensitivity level handling procedures during assembly. Validate that the T7 tape-and-reel packaging matches production line specifications. Ensure substitute parts maintain functional compatibility if original stock is unavailable.

Selection Notes

Select this component for designs requiring dedicated sync separation from composite video sources. Verify that the 8-SOIC package fits the PCB layout constraints. Confirm the 5V supply rail availability within the system architecture. Evaluate thermal management needs for the SOIC package in the final enclosure. Consider obsolescence risks when planning long-term production runs.

Part Context

The EL4581 belongs to Renesas' video processing family, specifically targeting sync separation tasks. It complements other video ICs like the EL4583 and EL4584 which handle broadcast-quality separation and clock generation respectively. The CS suffix indicates a commercial temperature range and SOIC package variant. This part serves as a specialized building block for analog video signal conditioning circuits.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The base model EL4581CS is listed as obsolete. Designers should consult manufacturer resources for current alternatives or evaluate pin-compatible successors within the Renesas portfolio.
