MC100EL34DR2

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100EL34DR2 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 = 4.2 V to 5.7 V) and NECL mode (VEE = −4.2 V to −5.7 V). Key electrical parameters include a maximum toggle frequency of 1.1 GHz, within-device skew of 100 ps, and cycle-to-cycle jitter of 1.0 ps. Power supply current is typically 39 mA at 5.0 V. It includes an internally generated VBB reference voltage pin and operates over a temperature range of -40°C to +85°C in an SO-16 package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm packaging type and lead-free status. The 'R2' suffix indicates tape and reel packaging containing 2500 units. Confirm RoHS compliance requirements if applicable, as 'G' suffix variants are explicitly marked as Pb-Free packages.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when precise alignment of divided clock edges is required due to its synchronous divider architecture. Ensure the design accommodates the 1.1 GHz maximum toggle frequency and the 39 mA typical power supply current. Verify compatibility with either PECL or NECL voltage levels based on the system's VCC and VEE configurations.
