EL4511CU

Overview

The EL4511CU is a Super Sync Separator integrated circuit manufactured by Intersil, designed for processing video signals in digital television and broadcast equipment. It accepts composite, component, HDTV, and PC signal inputs, automatically detecting sync formats including tri-level and bi-level syncs without external timing resistors. The device operates on 3.3V or 5V power supplies within a commercial temperature range of 0°C to +70°C. It is housed in a 24-pin QSOP package.

Feature Summary

• Automatically detects and locks to line rates up to 150kHz without requiring an external RSET resistor
• Compatible with composite, component, HDTV, and PC signal formats including tri-level and bi-level syncs
• Supports dual voltage operation at 3.3V and 5V levels

Applications

• HDTV and DTV analog input processing
• Video projector synchronization
• Computer monitor display systems
• Set-top box video decoding
• Broadcast video equipment

Procurement Notes

Verify the specific suffix (e.g., CUZ vs CU) against current Renesas documentation, as manufacturing transitions may affect RoHS compliance status and pinout details. Confirm availability through authorized distributors, noting that older Intersil stock may be subject to discontinuation notices. Ensure the procurement channel provides valid traceability for moisture sensitivity handling requirements.

Selection Notes

Select this component when automatic sync format 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 system power supply aligns with the supported 3.3V or 5V operating ranges and that the QSOP-24 package fits the PCB layout constraints.

Part Context

The EL4511 series represents Intersil's solution for advanced video sync separation in next-generation display applications. Following Renesas' acquisition of Intersil, these parts are managed under the Renesas portfolio. The device addresses the complexity of mixed-format video environments by eliminating manual configuration of sync parameters.

Replacement Considerations

Check Renesas official documentation for direct cross-references. The EL4511CUZ is the lead-free variant of this component. No other functional substitutes are confirmed in public data.
