EL4583CN

Overview

The EL4583CN is a video sync separator IC manufactured by Renesas Electronics Corporation (formerly Intersil). It extracts timing from NTSC, PAL, and SECAM video signals. The device operates on a single +5V supply within an industrial temperature range of -40°C to +85°C. It features precision 50% slicing using internal sample-and-hold circuits, a built-in programmable color burst filter, and multiple digital outputs including composite sync, vertical sync, horizontal sync, and odd/even field detection. The component is housed in a 16-lead PDIP package.

Feature Summary

• Extracts timing from standard and non-standard video formats
• Provides precision 50% sync slicing with hum rejection
• Includes a built-in programmable color burst filter
• Detects loss of signal via a dedicated output pin

Applications

• Video special effects processing
• Video test equipment synchronization
• Video distribution systems
• Multimedia display interfaces
• Video data capture triggers

Procurement Notes

Verify the specific ordering suffix for the 16-lead PDIP package configuration. Confirm that the manufacturer accepts orders for this discontinued or legacy part number. Ensure compatibility with existing PCB footprints designed for the original Intersil specifications before finalizing procurement plans.

Selection Notes

Select this component when precise sync separation is required for NTSC, PAL, or SECAM standards. The integrated sample-and-hold circuitry simplifies design by eliminating external components typically needed for accurate slice level determination. Verify that the application requires the specific output logic levels and timing characteristics provided by this device.

Part Context

This component belongs to the EL4583 family of video sync separators. It shares functional compatibility with other variants in the series, such as the EL4581, allowing for socket interchangeability in certain designs. The technology utilizes high-performance analog CMOS processes to achieve low power consumption while maintaining robust signal integrity across varying input amplitudes.

Replacement Considerations

Consult official documentation for confirmed substitute part numbers. Verify pinout compatibility and electrical specifications against alternative devices before implementation.
