MC10EP195MNG

Overview

The MC10EP195MNG is a programmable delay line manufactured by onsemi, designed for clock deskewing and timing adjustment. It provides variable delay of a differential NECL/PECL input transition with increments of 10 ps. The device operates in PECL mode with VCC ranging from 3.0 V to 3.6 V (VEE = 0 V) or NECL mode with VCC at 0 V and VEE from -3.0 V to -3.6 V. It features a maximum input clock frequency exceeding 1.2 GHz and a typical propagation delay of 2.5 ns. The component is housed in a QFN-32 package and supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Programmable delay functionality with 10 ps resolution for precise timing control
• Supports both PECL and NECL differential input/output signaling standards
• Includes safety clamps on inputs and open input default state protection
• Temperature compensated design within the 100 Series family

Applications

• Clock deskewing in high-speed digital systems
• Timing adjustment for data synchronization
• Skew management in communication interfaces

Procurement Notes

Verify the specific suffix MNG against official datasheets to confirm package type and moisture sensitivity level. Ensure compatibility with required supply voltages for PECL or NECL operation. Confirm RoHS compliance status and lead-free packaging requirements before procurement. Check for obsolescence notices or lifecycle changes directly from the manufacturer.

Selection Notes

Select this component when precise programmable delay is required for differential clock signals. Ensure the system voltage aligns with the specified 3.0 V to 3.6 V range for PECL operation. Consider the QFN-32 package constraints for PCB layout and thermal management. Verify that the 10 ps increment resolution meets the system's jitter and skew tolerance requirements.

Part Context

This part belongs to the MC10EP195B series of programmable delay chips. It is distinct from other logic families due to its specialized function in timing adjustment rather than standard logic operations. The device integrates temperature compensation to maintain performance across the industrial temperature range.

Replacement Considerations

Direct substitutes may include other parts from the MC10EP195 family with different suffixes indicating package variations. Verify functional equivalence regarding delay range and input/output standards before substitution.
