MC100EP196FAR2

Overview

The MC100EP196FAR2 is a programmable delay line from onsemi, designed for clock deskewing and timing adjustment. It operates within a supply voltage range of 3 V to 3.6 V and supports an operating temperature range of -40 °C to +85 °C. The device provides a propagation delay range of 2.36 ns to 12.258 ns with a resolution of approximately 10 ps. It features a QFN-32 package and includes digital select inputs for delay configuration.

Feature Summary

• Provides variable delay for differential NECL/PECL input transitions
• Features digitally selectable delay resolution for precise timing control
• Supports analog fine-tuning via FTUNE pin for additional delay adjustment

Applications

• Clock deskewing in high-speed digital systems
• Timing adjustment for data synchronization
• Programmable delay lines in communication equipment

Procurement Notes

Verify the exact suffix 'R2' against official datasheets, as standard listings often use 'FAG' or 'BMNG'. Confirm RoHS compliance status and moisture sensitivity level (MSL) before procurement. Check for end-of-life or not recommended for new design (NRND) status if applicable. Ensure packaging type matches production requirements.

Selection Notes

Select this component when precise programmable delay is required for ECL/PECL signals. Consider the 10 ps resolution and analog fine-tuning capability for applications needing sub-nanosecond accuracy. Verify that the QFN-32 package fits the PCB layout constraints. Compare performance against similar models like MC100EP196A if specific suffix variations are unavailable.

Part Context

This part belongs to the MC100EP196 series of programmable delay chips. It shares architectural similarities with the MC100EP195 but offers enhanced tunability through the FTUNE pin. The series is designed for high-speed timing applications requiring flexible delay settings without external components.

Replacement Considerations

MC100EP196A and MC100EP196B are functionally similar programmable delay lines. Verify pin compatibility and electrical specifications before substitution. The MC100EP196FAR2G is also listed as a variant with comparable delay ranges.
