MC100EP139DTR2

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100EP139DTR2 is a low skew clock generation chip designed for synchronous frequency division applications. It integrates ÷2/4 and ÷4/5/6 dividers with internal synchronization to align common output edges. The device supports PECL mode (VCC = 3.0 V to 5.5 V, VEE = 0 V) and NECL mode (VCC = 0 V, VEE = −3.0 V to −5.5 V). Key electrical parameters include a maximum frequency exceeding 1.0 GHz, typical power supply current of 87 mA at 25°C (PECL), and propagation delays ranging from 600 ps to 1000 ps depending on the path and temperature. It features a master reset input for system synchronization and an open-input default state.
