MC100EP40DT

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100EP40DT is a three-state differential phase-frequency detector designed for phase-locked loop applications requiring minimal phase and frequency difference at lock. It operates with 3.3 V or 5 V power supplies, supporting PECL (VCC = 3.0 V to 5.5 V) and NECL (VEE = -3.0 V to -5.5 V) modes. The device features advanced design to minimize the dead zone, ensuring accurate error voltage generation for VCO control when reference and feedback inputs differ in frequency or phase. It includes internal termination networks and a Phase Lock Detect pin that indicates lock when the phase difference is 80 ps or less.
