EL4583CSZ-T7S2687

Overview

The EL4583CSZ-T7 is a video sync separator integrated circuit manufactured by Renesas Electronics Corporation. It extracts timing from NTSC, PAL, and SECAM video signals using a precision 50% slice level determined by internal sample-and-hold circuits. The device operates on a single +5V supply and includes a built-in programmable color burst filter to prevent chroma interference. Key outputs include composite sync, vertical sync, horizontal sync, burst/back porch, odd/even field detection, and a no-signal detect flag. Timing functions are resistor-programmable via an external RSET component.

Feature Summary

• Extracts timing from standard and non-standard video formats
• Features a built-in programmable color burst filter
• Provides multiple digital sync outputs including horizontal and vertical
• Detects loss of input signal with a dedicated output pin

Applications

• Video special effects processing
• Video test equipment
• Video distribution systems
• Multimedia applications
• Displays and imaging systems

Procurement Notes

Verify the specific suffix 'T7' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status as the base part supports Pb-free options. Check current availability as this series may be subject to discontinuation notices. Ensure the supplier provides valid datasheets matching FN7173.3 for accurate electrical verification.

Selection Notes

Select this component for designs requiring precise sync separation from analog video sources. The internal sample-and-hold circuits provide robust noise immunity. Verify that the external RSET resistor meets the 1% tolerance requirement specified in the datasheet. Ensure the application environment stays within the -40°C to +85°C operating temperature range.

Part Context

This part belongs to the EL4583 family of sync separators produced by Intersil, now part of Renesas Electronics. The family includes variants such as the EL4583CN and EL4583CS. These devices are designed for broadcast-quality video processing and are compatible with standard video interfaces. The T7 suffix specifically denotes the reel packaging format for automated assembly.

Replacement Considerations

The EL4583CSZ package is pin-compatible with the 8-pin EL4581 socket design. Verify if the EL4583CS or EL4583CS-T13 variants meet the specific packaging requirements of the target assembly line.
