MC10EP139DWR2G

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC10EP139DWR2G is a low skew clock generation chip designed for precise timing applications. It integrates synchronous ÷2/4 and ÷4/5/6 dividers with internal alignment of common output edges. The device supports PECL (VCC = 3.0 V to 5.5 V, VEE = 0 V) and NECL (VCC = 0 V, VEE = −3.0 V to −5.5 V) modes. Key electrical parameters include a maximum frequency exceeding 1.0 GHz, typical power supply current of 83 mA at 25°C, and output-to-output skew of 50 ps. It features a master reset for synchronization and an internally generated VBB reference voltage.
