MC100EL38DWR2

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100EL38DWR2 is a clock generator integrated circuit manufactured by onsemi, belonging to the 100EL series. It features a single circuit with a differential NECL or PECL input and four differential ECL outputs, providing a 1:4 input-to-output ratio. The device supports maximum frequencies up to 1.2 GHz and operates on a supply voltage range of 4.2 V to 5.7 V. Packaged in a 20-SOIC (0.295", 7.50mm Width) surface-mount enclosure, it functions without an internal PLL and lacks frequency multiplication capabilities. The component is rated for operation between -40°C and +85°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Supports 1.2 GHz maximum operating frequency
• Converts one differential input to four differential ECL outputs
• Accepts NECL or PECL input signals
• Operates within a 4.2 V to 5.7 V power supply range

Clock Generators, PLLs, Frequency Synthesizers Applications

• High-speed clock distribution networks
• Telecommunications infrastructure timing systems
• Data communication equipment requiring low-jitter signal generation

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

The MC100EL38DWR2 is classified as obsolete and no longer manufactured. Verification should confirm availability through surplus channels or direct replacement parts such as the MC100EL38DWR2G. Buyers must account for the End-of-Life status when planning long-term production cycles.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component for applications requiring a 1:4 fanout from a differential source to ECL loads at speeds up to 1.2 GHz. Ensure the design accommodates the 4.2 V to 5.7 V supply requirement and the 20-SOIC package dimensions. Verify that the legacy status does not conflict with product lifecycle requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MC100EL family of high-speed ECL logic devices. It serves as a dedicated clock generator rather than a divider or multiplier. The 'DWR2' suffix indicates the specific tape-and-reel packaging variant of the 20-SOIC package.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The MC100EL38DWR2G is listed as a direct substitute. Both components share identical electrical specifications and pinouts, differing primarily in manufacturing compliance updates.
