MC100EP196FAG

Overview

The MC100EP196FAG is a programmable delay line manufactured by onsemi, designed for clock deskewing and timing adjustment in high-speed digital systems. It operates within a supply voltage range of 3 V to 3.6 V and supports differential NECL/PECL input transitions. The device provides a total variable delay range from approximately 2.36 ns to 12.258 ns with a resolution of about 10 ps per tap. It features 1024 selectable taps controlled via digital inputs and includes an FTUNE pin for analog fine-tuning of the output delay. Housed in a 32-VFQFN package, it functions as a single-channel delay element suitable for precision timing applications.

Feature Summary

• Programmable delay matrix with 1024 taps for precise digital timing control
• Analog fine-tuning capability via FTUNE pin for sub-nanosecond adjustments
• Supports differential NECL and PECL logic families for high-speed operation

Applications

• Clock deskewing in multi-clock domain systems
• Timing adjustment for high-speed data converters
• Precision pulse generation and synchronization circuits

Procurement Notes

Verify the specific suffix 'FAG' against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Check for Not Recommended for New Design (NRND) status or lifecycle changes before finalizing procurement plans. Ensure compatibility with existing PCB footprint requirements for the 32-VFQFN package.

Selection Notes

Select this component when precise, adjustable delay is required for differential ECL signals. Compare the 1024-tap resolution against simpler fixed-delay lines if finer granularity is needed. Verify that the 3V to 3.6V operating range aligns with the system power supply rails and that the thermal characteristics of the QFN package are adequate for the application environment.

Part Context

This part belongs to the MC100EP196 series of programmable delay chips from onsemi. It shares architectural similarities with the MC100EP195 but adds the FTUNE feature for enhanced delay tunability. The series is designed specifically for applications requiring accurate timing alignment in high-frequency communication and computing infrastructure.

Replacement Considerations

The MC100EP196BFAG is listed as an alias for this part number. Verify functional equivalence and package compatibility before substitution. No other direct cross-model replacements are confirmed in the provided documentation.
