MC100E195FNR2G

Overview

The MC100E195FNR2G is a programmable delay chip manufactured by onsemi, designed for clock deskewing and timing adjustment applications. It provides variable delay for differential NECL/PECL input transitions within the 100 Series family, which includes temperature compensation. The device operates with a supply voltage range of 4.2 V to 5.7 V and functions within an ambient temperature range of 0°C to +85°C. It is housed in a 28-PLCC package with J-leads and is supplied in tape and reel packaging for surface mount installation.

Feature Summary

• Provides programmable delay for differential clock signals to correct skew
• Features temperature-compensated delay characteristics for stability
• Supports standard ECL power supply voltages

Applications

• Clock deskewing in high-speed digital systems
• Timing adjustment in data communication interfaces
• Synchronization circuits requiring precise delay control

Procurement Notes

Verify the specific suffix FNR2G against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements before integration into the assembly process. Check for any recent product change notices that may affect pinout or electrical parameters.

Selection Notes

Select this component when a fixed delay line is insufficient and adjustable timing alignment is required for ECL-based architectures. Ensure the system design accommodates the 28-PLCC footprint and the specified 4.2 V to 5.7 V operating voltage range. Consider thermal management capabilities if multiple units are deployed in dense configurations.

Part Context

This part belongs to the MC100E series of ECL logic devices from onsemi. It serves as a specialized timing element within the broader portfolio of clock distribution and interface solutions. The device complements other ECL components by providing precise temporal alignment capabilities essential for high-frequency signal integrity.

Replacement Considerations

The MC100E195FN is listed as an alias. Verify if the non-G suffix variant meets identical electrical and mechanical specifications. Cross-reference with the MC100EP195 series for 3.3V ECL alternatives if system voltage standards differ.
