MC100EL34DR2G

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100EL34DR2G is a low skew clock generation chip designed for ÷2, ÷4, and ÷8 frequency division applications. It operates in PECL mode with VCC ranging from 4.2 V to 5.7 V (VEE = 0 V) or NECL mode with VEE from −4.2 V to −5.7 V (VCC = 0 V). The device features synchronous internal dividers ensuring aligned output edges, with a maximum toggle frequency of 1.1 GHz. Key electrical parameters include a typical power supply current of 39 mA, propagation delays up to 1200 ps from CLK to Q1/Q2, and within-device skew limited to 100 ps. It utilizes an SO-16 package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Low skew clock generation with 50 ps typical output-to-output skew
• Synchronous enable/disable logic prevents runt clock pulses during state changes
• Internal VBB pin provides a reference voltage for single-ended inputs or AC coupling rebiasing
• Master reset input allows synchronization of internal dividers and multiple devices

Clock Generators, PLLs, Frequency Synthesizers Applications

• Low skew clock distribution networks
• Synchronous frequency division systems
• PECL/NECL logic interface circuits

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix 'R2G' corresponds to the SO-16 tape and reel packaging configuration containing 2500 units per reel. Confirm RoHS compliance status as indicated by the 'G' suffix in the manufacturer's documentation. Ensure the procurement source references the official datasheet publication number MC10EL34/D for accurate technical specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when precise alignment of divided clock edges is required due to its synchronous internal divider structure. Choose between MC10EL34 and MC100EL34 variants based on temperature compensation requirements, as the 100 Series includes internal temperature compensation. Ensure the design supports the 75 kΩ internal input pulldown resistors on CLK, EN, and MR pins for proper default states.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MC10/100EL34 family of 5V/EnECL clock generation chips. It is distinct from other series members like the MC100EL32 (divider) or MC100EL51 (flip-flop) by integrating ÷2, ÷4, and ÷8 functions into a single package with common enable and master reset controls.
