MC100E195FNR2

Overview

The MC100E195FNR2 is a programmable delay chip manufactured by onsemi, designed for clock deskewing and timing adjustment in high-speed digital systems. It operates within the MC100E series, supporting differential NECL/PECL input transitions with a maximum input clock frequency exceeding 1.2 GHz. The device provides a programmable delay range of 2.2 ns to 12.2 ns with 10 ps increments. It functions at a supply voltage of 4.2 V to 5.7 V, housed in a 28-PLCC package suitable for surface mount installation, and operates within a temperature range of 0°C to +85°C.

Feature Summary

• Provides variable delay for differential NECL/PECL input transitions to manage clock skew
• Features temperature compensation within the 100 Series architecture
• Includes safety clamps on inputs and an open input default state
• Supports flexible logic input levels for control pins via D[10:0]

Applications

• Clock deskewing in high-frequency data communication systems
• Timing adjustment in serial link transceivers
• Phase alignment in multi-channel synchronization circuits

Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm RoHS compliance status and specific packaging details such as reel quantity prior to ordering. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent damage during soldering processes.

Selection Notes

Select this component when precise sub-nanosecond delay tuning is required for ECL-based architectures. Compare against fixed-delay buffers if static timing offsets suffice. Consider the MC100EP195BMNG for lower voltage PECL applications requiring QFN packaging instead of PLCC.

Part Context

This part belongs to the MC100E family of high-speed ECL components from onsemi. It complements other clock distribution devices like the MC100E211FNR2 by adding programmable delay capabilities rather than simple buffering. The FNR2 suffix indicates tape and reel packaging for automated assembly.

Replacement Considerations

The MC100E195FN is the tube-packaged equivalent of this component. For lower voltage operations, the MC100EP195 series offers similar functionality with different power requirements.
