MC100LVEL34DR2

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100LVEL34DR2 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 precisely. 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 electrical parameters include a maximum toggle frequency of 1.5 GHz, typical output-to-output skew of 50 ps, and cycle-to-cycle jitter under 1 ps. Power supply current ranges from 40 mA to 62 mA depending on temperature. It includes a master reset for synchronization and a synchronous enable input.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the package suffix 'R2' corresponds to the SO-16 reel packaging containing 2500 units per reel as specified in the ordering information. Confirm the specific revision level required for the design. Ensure compatibility with the manufacturer's RoHS and REACH compliance declarations prior to procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when synchronous frequency division with minimal skew is required between ÷2, ÷4, and ÷8 outputs. Ensure the design accommodates the 40–62 mA power supply current range. Verify that the input signal swing meets the minimum 150 mV requirement for guaranteed AC parameters. Consider the thermal resistance characteristics if operating at high ambient temperatures.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MC100LVEL series, which contains temperature-compensated ECLinPS devices. The 'D' suffix indicates an SO-16 package, while 'R2' denotes tape and reel packaging. Other variants include the DT suffix for TSSOP-16 packages. The series is designed for high-speed applications requiring robust ECL performance.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include MC100LVEL34D (SO-16 tube) or MC100LVEL34DT/TSSOP-16. Ensure any substitute maintains the synchronous divider architecture and low skew specifications. Verify pinout compatibility and electrical parameter equivalence for PECL/NECL operation.
