MC10EL34DR2G

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC10EL34DR2G is a low skew ÷2, ÷4, ÷8 clock generation chip designed for precise clock alignment. It features synchronous internal dividers and an internally generated VBB reference voltage. The device supports PECL (VCC = 5.0 V) and NECL (VEE = -5.0 V) modes with a maximum toggle frequency of 1.1 GHz. Key electrical parameters include a typical power supply current of 39 mA, propagation delays ranging from 750 ps to 1200 ps depending on the output stage, and within-device skew limited to 100 ps. It operates over a temperature range of -40°C to +85°C in an SO-16 package.
