MC100EP139DT

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100EP139DT is a low skew clock generation chip from the MC100EP series, designed for ÷2/4 and ÷4/5/6 frequency division. It features synchronous internal dividers to ensure precise alignment of common output edges. The device supports PECL mode with VCC ranging from 3.0 V to 5.5 V (VEE = 0 V) and NECL mode with VCC at 0 V and VEE from −3.0 V to −5.5 V. Maximum operating frequency exceeds 1.0 GHz typical. Key electrical parameters include a maximum propagation delay of 800 ps (CLK to Q), 50 ps output-to-output skew, and power supply current of 70 mA to 110 mA depending on temperature and voltage conditions.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Low skew design with 50 ps output-to-output skew and 200 ps device-to-device skew
• Synchronous enable/disable and master reset inputs for system synchronization
• Integrated VBB reference output for single-ended input biasing or AC coupling rebiasing
• Temperature compensated operation within the MC100 Series

Clock Generators, PLLs, Frequency Synthesizers Applications

• Low skew clock generation applications
• Clock distribution systems requiring precise edge alignment
• High-speed digital systems utilizing ECL logic families

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and shipping configuration. The DT suffix corresponds to the TSSOP-20 Wide Body package. Confirm RoHS compliance status as indicated in the ordering information table, noting that Pb-Free variants typically carry a 'G' suffix in the full part number.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when synchronous frequency division with minimal skew is required between multiple outputs. Ensure the power supply configuration matches either PECL (VCC 3.0-5.5 V, VEE 0 V) or NECL (VCC 0 V, VEE -3.0 to -5.5 V). Verify that the thermal resistance characteristics of the TSSOP-20 package are sufficient for the intended ambient temperature and airflow conditions.
