EL4511CUZ

Overview

The EL4511CUZ is a Super Sync Separator IC manufactured by Renesas Electronics, designed for processing video signals in digital television and broadcast equipment. It accepts composite, component, HDTV, PC, separate sync, and H/V sync inputs, automatically selecting the relevant format. The device detects and decodes tri-level syncs used in HD systems and automatically locks to the line rate without an external RSET resistor. It operates on 3.3V or 5V power supplies within a temperature range of 0°C to +70°C and is housed in a 24-pin QSOP package.

Feature Summary

• Automatically detects and locks to video line rates without requiring external timing resistors
• Compatible with composite, component, HDTV, PC, tri-level, and bi-level sync formats
• Integrated decoding for tri-level syncs utilized in high-definition systems

Applications

• HDTV and DTV analog input processing
• Video projector synchronization
• Computer monitor signal separation
• Set-top box video processing
• Broadcast video equipment

Procurement Notes

Verify the specific suffix 'Z' against official documentation to confirm RoHS compliance status, as legacy Intersil data sheets may list Pb-Free Plus Anneal availability separately. Confirm current lifecycle status, as this component series has been subject to discontinuance notifications. Ensure the 24-pin QSOP package matches your PCB footprint requirements before procurement.

Selection Notes

Select this component when automatic sync detection is required without external timing components. It is suitable for designs needing compatibility with both standard definition and high-definition tri-level sync signals. Verify that the 0°C to +70°C operating temperature range meets your environmental specifications. Consider the 3.3V/5V dual voltage operation for flexible power supply design.

Part Context

The EL4511CUZ belongs to the EL4511 series of video interface ICs originally developed by Intersil Corporation before its acquisition by Renesas Electronics. This series focuses on super sync separation for next-generation display applications. The part integrates advanced detection capabilities to simplify circuit design by eliminating the need for external resistor networks typically required for frequency locking.

Replacement Considerations

Check for official End-of-Life (EOL) notifications from Renesas. No direct public substitute part numbers are confirmed in the provided documentation. Evaluate pin-compatible alternatives only if officially documented by the manufacturer.
