ML6430CH

Overview

The ML6430CH is a multi-standard single-chip BiCMOS video Genlock integrated circuit manufactured by Micro Linear Corporation and distributed by Rochester Electronics. Designed for NTSC, PAL, and VGA applications, it generates stable clocks from analog video signals to provide timing pulses for clamping, decoding, blanking, and processing. The device handles VCR glitches, head switching variations, tape dropouts, missing sync pulses, freeze frames, high-speed playback, and camcorder gyro errors. It features line-locked scalable horizontal pixel clocks, standard frequencies of 12.27, 13.5, or 14.75 MHz, and audio clocks locked to video with low jitter characteristics.

Feature Summary

• Generates stable clocks from analog video signals for NTSC, PAL, and VGA standards
• Handles VCR glitches, head switching, tape dropouts, and missing sync pulses
• Provides line-locked scalable horizontal pixel clocks and standard frequencies (12.27, 13.5, 14.75 MHz)
• Features low clock jitter: Short Term <200ps rms, Line-to-Line <600ps rms

Applications

• Video signal processing systems requiring precise synchronization
• VCR and camcorder signal handling for glitch recovery
• Broadcast equipment supporting NTSC, PAL, and VGA formats

Procurement Notes

Verify the component's authenticity and lot traceability through authorized distributors or certified suppliers. Confirm the manufacturing date code and storage conditions to ensure reliability. Check for any specific handling requirements related to its BiCMOS technology and legacy status.

Selection Notes

Select this component when a robust solution for multi-standard video genlocking is required, particularly in environments with analog signal instability such as VCR playback. Ensure compatibility with existing serial control bus interfaces or preset configurations for standalone operation.

Part Context

Distributed by Rochester Electronics, LLC, the ML6430CH is a legacy part originally produced by Micro Linear Corporation. It belongs to a family of video synchronization ICs designed for professional and consumer video applications before being superseded by newer digital solutions.

Replacement Considerations

The ML6431 is a similar part within the same family. Verify pinout and functional compatibility if substituting. No direct modern equivalents are listed in public documentation.
