EL1881CS-T13

Overview

The EL1881CS-T13 is a video sync separator manufactured using high-performance analog CMOS process technology. It extracts sync timing information from standard and non-standard video inputs, providing composite sync, vertical sync, burst/back porch timing, and odd/even field detection. The device features fixed 70mV sync tip slicing for edge detection when the video input level ranges between 0.5VP-P and -2VP-P. A single external resistor sets all internal timing to accommodate various video standards. It operates on a single +5V supply with a typical low supply current of 1.5mA.

Feature Summary

• Extracts sync timing information from both standard and non-standard video inputs
• Provides composite sync, vertical sync, burst/back porch timing, and odd/even field detection outputs
• Features fixed 70mV sync tip slicing for reliable sync edge detection across specified input levels
• Utilizes a single external resistor to configure internal timing for diverse video standards

Applications

• Video amplifiers
• PCMCIA applications
• A/D drivers
• Line drivers
• Portable computers

Procurement Notes

Verify component authenticity through authorized Renesas distributors or official channels. Confirm package integrity and pin alignment against datasheet specifications. Check manufacturing date codes for potential obsolescence or lifecycle changes. Ensure storage conditions comply with moisture sensitivity level requirements to prevent damage prior to assembly.

Selection Notes

Select this component for designs requiring precise sync separation from composite video signals without complex external timing networks. Consider its low power consumption and single-supply operation for portable or battery-powered systems. Evaluate compatibility with target video standards such as NTSC, PAL, and SECAM based on the single-resistor timing configuration capability.

Part Context

The EL1881CS belongs to the EL1881 series of video interface integrated circuits produced by Renesas Electronics (formerly Intersil). This series focuses on signal conditioning and synchronization tasks in video processing chains. The T13 suffix typically denotes tape and reel packaging for automated surface-mount assembly, distinguishing it from bulk or tube variants.

Replacement Considerations

Cross-reference with other EL1881 variants like EL1881CS or EL1881CS-T7 for packaging differences. Verify functional equivalence with newer Renesas video sync separators if available. Ensure any substitute maintains the same 70mV slicing threshold and single-resistor timing architecture.
