MC10E195FNR2G

Overview

The MC10E195FNR2G is a 5V ECL Programmable Delay Chip manufactured by onsemi. It provides variable delay for differential NECL/PECL input transitions, featuring a programmable range from 0 ns to 10 ns with 10 ps increments. The device supports a maximum input clock frequency exceeding 1.2 GHz and includes temperature compensation within the 100 Series architecture. It operates in PECL mode with VCC between 3.0 V and 3.6 V (VEE = 0 V) or NECL mode with VCC at 0 V and VEE between −3.0 V and −3.6 V. The component is housed in a 28-PLCC package, offers safety clamps on inputs, and accepts D[10:0] data inputs compatible with ECL, LVCMOS, or LVTTL logic levels.

Feature Summary

• Provides precise programmable delay adjustment for clock deskewing and timing alignment applications
• Features open input default state and safety clamps on inputs to ensure stable operation during undefined states
• Supports flexible digital control inputs accepting ECL, LVCMOS, or LVTTL logic levels for configuration

Applications

• Clock deskewing in high-speed communication systems
• Timing adjustment in digital signal processing circuits
• Programmable delay lines for synchronization tasks

Procurement Notes

Verify the specific suffix FNR2G against the manufacturer's current datasheet to confirm packaging details and environmental compliance status. Confirm availability as the base product may have obsolete variants. Ensure voltage supply requirements match the intended PECL or NECL operating mode before integration into the design.

Selection Notes

Select this component when precise sub-nanosecond delay adjustments are required for differential ECL signals. Consider the 10 ps increment resolution for fine-tuning timing margins. Verify that the system power supply can support the specified PECL or NECL voltage ranges and that the 28-PLCC package fits the PCB layout constraints.

Part Context

This part belongs to the MC10E series of 5V ECL components designed for high-speed digital applications. It shares functional similarities with other programmable delay chips like the MC100EP195 but operates at different voltage levels. The series is intended for applications requiring robust timing control in telecommunications and computing infrastructure.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate the MC100EP195B for similar functionality if voltage level differences can be accommodated, but verify pin compatibility and electrical specifications independently.
