MC100EP40DTR2

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100EP40DTR2 is a three-state 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 in PECL or NECL modes. The device features fully differential R, FB, UP, and DOWN inputs/outputs with internal 50 Ω termination networks on input pins. Key electrical parameters include a maximum frequency exceeding 2 GHz, typical propagation delays of 400–775 ps depending on mode and temperature, and output rise/fall times of 60–160 ps. Power supply current ranges from 100 mA to 170 mA across operating temperatures.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix 'R2' corresponds to the tape and reel packaging configuration specified in the datasheet. Confirm that the component is Pb-Free as indicated by the marking diagram. Ensure the procurement matches the TSSOP-20 package type and check for any specific moisture sensitivity level updates referenced in the revision history.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a three-state phase-frequency detector with low dead zone is required for ECL-based PLLs. Ensure input edge rates are less than 5 ns for proper operation. Verify power supply compatibility with either PECL (3.0 V to 5.5 V) or NECL (0 V to -5.5 V) configurations. Consider thermal management if operating at elevated temperatures with high voltage differentials.
