MC100EP139DTR2G

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100EP139DTR2G is a high-speed clock generator manufactured by onsemi, designed for ECL logic families. It operates within a supply voltage range of 3 V to 5.5 V and supports maximum output frequencies up to 1 GHz. The device features four differential outputs with a maximum jitter of 0.2 ps and a duty cycle of 50%. It draws 95 mA of operating power current and functions reliably across an extended temperature range from -40°C to +85°C. Housed in a 20-lead SOIC package, this component serves as a critical timing element in high-frequency digital systems.

• Available in 20-SOIC surface-mount package

Clock Generators, PLLs, Frequency Synthesizers Applications

• High-speed data communication systems requiring precise clock distribution
• Telecommunications infrastructure utilizing ECL logic standards
• Test and measurement equipment demanding low-jitter clock signals

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify RoHS compliance status through official manufacturer documentation, as the non-G suffix variant indicates non-compliance while the G suffix typically denotes Green/RoHS adherence. Confirm moisture sensitivity level (MSL) handling requirements prior to assembly. Ensure the specific ordering suffix matches the required packaging format, as tape-and-reel specifications may vary between manufacturing runs or regional distributions.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-ratio clock generator with differential ECL outputs is required for frequencies approaching 1 GHz. The 0.2 ps jitter specification makes it suitable for applications sensitive to phase noise. Verify that the system power supply can maintain stability within the 3 V to 5.5 V range to ensure optimal performance and prevent timing errors during operation.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MC100EP series, which focuses on high-performance ECL logic devices. It is functionally related to the MC100EP139DW but differs in packaging, utilizing a tape-and-reel configuration instead of tube packaging. The 'G' suffix distinguishes it as a lead-free/RoHS-compliant version compared to earlier iterations in the product line.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The MC100EP139DTG is listed as an alias for this component. Direct substitution requires verifying identical pinout compatibility and ensuring the replacement unit meets the same 1 GHz frequency and 0.2 ps jitter specifications.
