EL4583CS-T13

Overview

The EL4583CS-T13 is a video sync separator IC manufactured by Renesas Electronics Corporation. It extracts timing from NTSC, PAL, and SECAM video signals using a precision 50% slice level derived from internal sample-and-hold circuits tracking the sync tip and back porch. The device operates on a single +5V supply within an industrial temperature range of -40°C to +85°C. It features a built-in programmable filter for color burst attenuation and provides multiple outputs including composite sync, vertical sync, horizontal sync, and odd/even field detection. The component is housed in a 16-lead SOIC package.

Feature Summary

• Extracts timing from standard and non-standard video formats using a 50% sync slice level determined by internal sample-and-hold circuits.
• Includes a built-in programmable active filter to attenuate chroma signals and prevent interference with sync separation.
• Provides dedicated outputs for composite sync, vertical sync, horizontal sync, and odd/even field identification.
• Features a TTL/CMOS compatible no signal detect output to flag input signal loss or amplitude reduction.

Applications

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

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence notices. Confirm that the specific T13 tape and reel packaging matches system assembly requirements. Ensure compatibility with RoHS standards if lead-free compliance is mandatory for the final product assembly process.

Selection Notes

Select this component when precise timing extraction from analog video sources is required without external filtering complexity. The integrated sample-and-hold mechanism ensures stable operation across varying input signal amplitudes. Consider the 16-lead SOIC footprint for board space constraints and verify that the single 5V supply aligns with the target system power architecture.

Part Context

This device belongs to the EL4583 family of video synchronization processors. It shares functional similarities with the EL4581 but utilizes a 16-lead package instead of an 8-lead configuration. The technology leverages high-performance analog CMOS processes to deliver low-power operation while maintaining robust noise immunity and signal integrity for professional video applications.

FAQ

How is the 50% sync slice level determined?

The 50% slice level is established by two internal sample-and-hold circuits that track the sync tip and back porch levels, providing hum and noise rejection.

What is the function of the Level Output pin?

The Level Output pin provides an analog voltage signal with twice the sync pulse amplitude, which can be used to control an external Automatic Gain Control (AGC) function.

How does the device handle missing serration pulses?

If the input video lacks valid vertical interval serration pulses, the device produces a default vertical output based on an internal timer.
