GS4981-IDA

Video Processing Overview

The GS4981-IDA is a monolithic video sync separator IC designed for NTSC, PAL, and SECAM standards. It operates on a supply voltage range of 4.5V to 13.2V. The device generates composite sync, vertical sync, back porch, and horizontal sync signals. It is housed in an 8-PDIP package.

Video Processing Feature Summary

• Generates composite sync, vertical sync, back porch, and horizontal sync signals from input video
• Compatible with NTSC, PAL, and SECAM video standards
• Operates within a wide supply voltage range of 4.5V to 13.2V

Video Processing Applications

• Professional video signal processing
• Video synchronization circuits
• Broadcast equipment signal conditioning

Video Processing Procurement Notes

Verify the specific suffix IDA confirms the 8-PDIP package and Gennum manufacturing origin. Ensure compatibility with required voltage ranges and video standards before integration. Cross-reference datasheet revisions for any pinout or electrical characteristic updates.

Video Processing Selection Notes

Select this component when horizontal sync output is required instead of odd/even field signals. Compare against the GS4881 variant if vertical sync and back porch generation are sufficient without horizontal sync extraction. Confirm package availability matches PCB layout constraints.

Video Processing Part Context

The GS4981 series includes general-purpose sync separators like the GS1881 and GS4881. The GS4981-IDA specifically differs from the GS4881 by providing horizontal sync output rather than odd/even field outputs. This makes it suitable for applications requiring standard horizontal timing information.

Video Processing Replacement Considerations

The GS4881 is a related variant that provides odd/even field outputs instead of horizontal sync. Verify functional requirements to determine if the GS4881 is a suitable alternative.
