EL4583AISZ

Overview

The EL4583AISZ is a video sync separator integrated circuit manufactured by Renesas Electronics Corporation. It supports NTSC, PAL, and SECAM standards within a 16-SOIC package. The device operates on a 5V supply voltage with an industrial temperature range of -40°C to +85°C. It features a 50% slice level for synchronization signal extraction and includes sample-and-hold filtering capabilities. The component is classified as end-of-life.

Feature Summary

• Extracts synchronization signals from composite video inputs compatible with NTSC, PAL, and SECAM formats.
• Incorporates internal sample-and-hold filtering to improve signal integrity during separation.
• Utilizes a fixed 50% threshold slice level for consistent sync pulse detection.

Applications

• Professional video processing systems
• Video monitoring equipment
• Broadcast signal conditioning circuits

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Availability is restricted to existing stock or obsolete channels. Verify RoHS compliance status and moisture sensitivity levels before integration into new designs due to discontinuation risks.

Selection Notes

Select this part only for legacy system maintenance or repair where original specifications are mandatory. Evaluate alternative modern video sync separators if designing new hardware, as supply continuity cannot be guaranteed. Ensure compatibility with 16-SOIC footprints and 5V logic levels.

Part Context

Part of the EL4583A series, which focuses on analog video signal processing. The 'I' suffix typically denotes industrial temperature grading. Manufactured under the Intersil brand heritage now held by Renesas Electronics.

Replacement Considerations
