MC100EL38DWR2G

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100EL38DWR2G is a clock generator integrated circuit from the onsemi 100EL series, designed for high-speed differential signaling applications. It operates within a supply voltage range of 4.2V to 5.7V and supports input signals compatible with NECL and PECL standards. The device features a single circuit configuration with a maximum operating frequency of 1.2GHz. It provides four differential ECL outputs derived from one differential input, maintaining a 1:4 input-to-output ratio. The component is housed in a 20-SOIC package (0.295 inch width) suitable for surface mount installation. It functions reliably across an industrial temperature range of -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify RoHS compliance status as the non-G suffix variant was previously non-compliant; confirm current manufacturing status via official distributor channels. Check for moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Ensure the ordering suffix matches the specific package and environmental certification needed for the design.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed 1:4 clock fan-out without programmable division or multiplication is required. Verify that the system power supply falls within the 4.2V to 5.7V range. Confirm compatibility with NECL or PECL input drivers and ECL load requirements. Consider the 20-SOIC footprint constraints against available PCB real estate.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MC100EL38 family of clock generators. The 'G' suffix typically indicates Green/RoHS-compliant packaging and material composition compared to older variants like the MC100EL38DWR2. It serves as a direct replacement for previous non-compliant versions while maintaining identical electrical and mechanical specifications.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The MC100EL38DWR2G is listed as a direct substitute for the discontinued MC100EL38DWR2. No other cross-model substitutes are publicly confirmed for this specific part number.
