ML2021IS

Video Processing Overview

The ML2021IS is a monolithic CMOS phase-locked loop (PLL) synthesizer designed for frequency synthesis applications. It integrates a reference divider, phase-frequency detector, charge pump, voltage-controlled oscillator (VCO) driver, and output dividers into a single package. The device supports integer-N synthesis architectures and provides flexible clock generation capabilities for communication systems.

Video Processing Feature Summary

• Integrates complete PLL functions including phase detector and charge pump
• Supports programmable reference and feedback division ratios
• Includes VCO drive capability for direct oscillator control
• Provides multiple output divider options for frequency scaling

Video Processing Applications

• Frequency synthesizers for wireless communication transceivers
• Clock generation modules in base station equipment
• Local oscillator sources for RF receivers
• Test and measurement instrument frequency references

Video Processing Procurement Notes

Verify the specific suffix 'IS' against the manufacturer's official datasheet to confirm temperature range and package variant. Ensure compatibility with existing VCO specifications and reference clock frequencies before procurement. Cross-reference pinouts with current production revisions to avoid integration errors.

Video Processing Selection Notes

Select this component when a fully integrated PLL solution is required without external analog filters. Evaluate the maximum operating frequency limits against the target application bandwidth. Consider the power supply requirements and noise sensitivity of the integrated charge pump relative to system performance needs.

Video Processing Part Context

Fairchild Semiconductor, now part of ON Semiconductor, produced the ML2021 series as part of their analog mixed-signal portfolio. This family targets high-performance frequency synthesis needs in telecommunications infrastructure. The ML2021IS represents a specific industrial or commercial grade variant within this established product line.

Video Processing Replacement Considerations

Consult official cross-reference lists for direct replacements such as the ML2021 series variants from ON Semiconductor. Verify functional equivalence regarding pinout and register configuration before substituting.
