ML6420CS1

Overview

The ML6420CS1 is a monolithic BiCMOS sixth-order filter designed for fixed-frequency low-pass video applications. It provides triple output phase-equalized filtering, primarily intended for input anti-aliasing in video signal chains. The device operates on a single 5V ±10% supply and requires no external components or clocks. It offers selectable bandwidths of 3.0, 5.5, 8.0, or 9.3 MHz with gain options of 1X or 2X. Key performance metrics include greater than 40dB stopband rejection, less than 2% differential gain, and less than 2 degrees differential phase. It can drive loads of 1VP-P into 75Ω or 2VP-P into 150Ω.

Feature Summary

• Triple output phase-equalized architecture for consistent video signal integrity
• Integrated sixth-order filter with equalizer eliminating need for external passive components
• High stopband rejection exceeding 40dB to effectively suppress high-frequency noise
• Low distortion characteristics ensuring minimal differential gain and phase errors

Applications

• Input anti-aliasing filtering for video processing systems
• Fixed frequency low-pass filtering in analog video circuits
• Signal conditioning for composite video signals requiring precise bandwidth control

Procurement Notes

Verify the manufacturer origin carefully as Micro Linear Corporation was acquired by ON Semiconductor. Confirm the specific suffix designation matches the required bandwidth and gain configuration. Check current availability status as older BiCMOS video filters may be discontinued or subject to last-time buys. Ensure the package type aligns with the target PCB layout requirements.

Selection Notes

Select this component when a complete, clockless sixth-order video filter solution is required without external tuning. Compare bandwidth options (3.0, 5.5, 8.0, 9.3 MHz) against the specific video standard being processed. Evaluate the gain setting (1X vs 2X) based on the source impedance and load driving requirements. Consider the operating temperature range and supply voltage tolerance for system compatibility.

Part Context

This part belongs to the ML6420 series of video filters from Micro Linear Corporation. It is functionally related to the ML6421 series, which offers sinx/x equalization instead of phase equalization. The CS1 suffix typically denotes a specific commercial grade temperature range and packaging variant within the broader ML6420 family.

Replacement Considerations

Direct substitutes include other ML6420 variants with different bandwidth suffixes if the frequency response differs. The ML6421 series serves as an alternative if sinx/x equalization is preferred over phase equalization. Verify pinout compatibility before swapping with similar video filters from other manufacturers.
