MC100LVEL34DG

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100LVEL34DG is a low skew clock generation chip designed for ÷2, ÷4, and ÷8 frequency division. It features synchronous internal dividers that align common output edges with typical output-to-output skew of 50 ps. The device supports PECL mode (VCC = 3.0 V to 3.8 V) and NECL mode (VEE = −3.0 V to −3.8 V). Key specifications include a maximum toggle frequency of 1.5 GHz, cycle-to-cycle jitter less than 1 ps, and propagation delays ranging from 500 ps to 700 ps depending on the path. It includes a master reset for synchronization and a synchronous enable input.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the package suffix 'DG' corresponds to the SO-16 (D Suffix) variant as listed in the ordering information. Confirm supply voltage requirements match either PECL or NECL modes. Ensure proper decoupling of the VBB pin if used for single-ended inputs or AC coupling rebiasing, limiting current to 0.5 mA.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when precise alignment of multiple divided clock signals is required. The synchronous enable feature prevents glitch generation during state changes. Verify that the input signal swing meets the minimum 150 mV requirement for guaranteed AC parameters. Consider thermal resistance values if operating at high frequencies without airflow.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The MC100LVEL34 belongs to the 100LVEL series, which incorporates temperature compensation. It is part of the ECLinPS family designed for high-performance logic applications. The device integrates 210 transistors and provides dedicated VBB reference voltage output for input biasing.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Check for other members of the 100LVEL series such as the MC100LVEL33 or MC100LVEL35 if different division ratios are needed. Ensure any substitute maintains the same SO-16 package dimensions and electrical characteristics for direct replacement.
