FMS6143CS

Overview

The FMS6143CS is a low-cost, three-channel video filter driver manufactured by Fairchild Semiconductor. It integrates a fourth-order standard definition video filter with a driver stage, designed for composite and S-video signal processing. The device features three independent channels to handle luminance and chrominance signals simultaneously. It operates within a single supply voltage range, typically compatible with standard consumer electronics power rails. The component utilizes surface-mount packaging to facilitate compact printed circuit board layouts in portable and fixed video equipment applications.

Feature Summary

• Integrates third-order active filters with output drivers for composite and S-video signals
• Provides three independent signal processing channels for simultaneous video path handling
• Designed for standard definition video applications requiring low cost and small footprint

Applications

• Composite video signal conditioning in consumer electronics
• S-video input buffering and filtering
• Portable media players and handheld video devices
• Set-top boxes and digital video recorders

Procurement Notes

Verify the exact suffix designation against the manufacturer's current datasheet, as variations may exist between FMS6143C and FMS6143CSX. Confirm package type compatibility during PCB design review. Ensure supply chain sources provide original manufacturer documentation to validate pinout and electrical characteristics before integration into production designs.

Selection Notes

Select this component for applications requiring integrated filtering and driving of standard definition video signals without external passive components. Consider channel count requirements carefully as it provides exactly three paths. Evaluate power supply constraints to ensure compatibility with the device's operating voltage range. Compare performance metrics such as bandwidth and distortion against alternative drivers if high-fidelity video reproduction is critical.

Part Context

Fairchild Semiconductor developed the FMS series for the consumer video market, focusing on simplifying analog video front-ends. This part belongs to a family of integrated filter drivers that replaced discrete RC networks and separate amplifier stages. The technology allows manufacturers to reduce bill-of-materials costs while maintaining signal integrity in budget-friendly video playback and recording hardware.

Replacement Considerations

Check for direct replacements from ON Semiconductor following their acquisition of Fairchild's semiconductor business. Verify functional equivalence regarding filter order and channel configuration when substituting.
