MC10EP139DW

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC10EP139DW is a low skew clock generation chip from the 10EP series, designed for ÷2/4 and ÷4/5/6 frequency division. It operates with differential ECL inputs (CML, NECL, PECL) and provides four differential ECL outputs. The device supports maximum frequencies exceeding 1.0 GHz with typical output-to-output skew of 50 ps. It functions within a power supply range of 3.0 V to 5.5 V for PECL mode or -3.0 V to -5.5 V for NECL mode. The component is housed in a 20-lead SOIC wide body package.
