MC100EP139DWR2G

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100EP139DWR2G is a low skew clock generation chip from the 100 Series, designed for synchronous ÷2/4 and ÷4/5/6 frequency division. It features internal dividers aligned to common output edges with a maximum output-to-output skew of 50 ps. The device supports PECL mode (VCC = 3.0 V to 5.5 V, VEE = 0 V) and NECL mode (VCC = 0 V, VEE = −3.0 V to −5.5 V). Typical maximum operating frequency exceeds 1.0 GHz. Power supply current ranges from 70 mA to 110 mA depending on voltage and temperature. It includes a master reset for synchronization and an internally generated VBB reference pin.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Synchronous enable/disable logic prevents runt clock pulses
• Configurable divide ratios: ÷2 or ÷4 for Q0/Q1; ÷4, ÷5, or ÷6 for Q2/Q3
• Pb-Free, Halogen Free, and RoHS Compliant

Clock Generators, PLLs, Frequency Synthesizers Applications

• Low skew clock generation applications
• System synchronization requiring precise edge alignment
• ECL-based high-speed digital systems

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that all VCC and VEE pins are externally connected to power supplies to guarantee proper operation. Ensure the exposed pad is attached to a heat-sinking conduit if using compatible packages. Confirm compliance with moisture sensitivity levels specified in the datasheet attributes table before assembly.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when differential ECL inputs and outputs are required with specific divide-by-2, 4, 5, or 6 ratios. The DW suffix indicates a SOIC-20 Wide Body package. Verify that the application environment stays within the -40°C to +85°C operating temperature range and that input voltage swings match the PECL or NECL specifications.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MC10/100EP139 family, which includes variants like MC10EP139 and MC100EP139. The '100' prefix denotes temperature compensation features included in the 100 Series. The 'G' suffix confirms the package is Pb-Free. Other package options include TSSOP-20 (DT suffix) and QFN-20 (MN suffix).

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes within the same family include MC100EP139DWG (tube packaging) or MC100EP139DTR2G (TSSOP-20 tape & reel). Cross-package replacements require verifying pinout compatibility and thermal characteristics.
