MC100LVEL34DR2G

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100LVEL34DR2G is a low skew clock generation chip designed for ÷2, ÷4, and ÷8 frequency division. It features synchronous internal dividers with precisely aligned common output edges. 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 less than 1 ps. Power supply current ranges from 40 mA to 62 mA in PECL mode and 23 mA to 40 mA in NECL mode. It operates within a temperature range of −40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the component status as discontinued before procurement. Confirm that the DR2G suffix corresponds to the SOIC-16 package in tape and reel format. Ensure design reviews account for the discontinuation status to avoid future supply constraints.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when low skew and synchronous division are required. Verify power supply requirements match either PECL or NECL specifications. Consider the 1.5 GHz maximum toggle frequency limit. Check if the SOIC-16 package fits the board layout constraints.
