MC100EP40DTG

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100EP40DTG is a three-state phase-frequency detector designed for phase-locked loop applications requiring minimal phase and frequency difference at lock. It features advanced design to significantly reduce the detector dead zone. The device 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. It includes internal 50 Ω termination resistors on reference and feedback inputs. Maximum operating frequency exceeds 2 GHz, with typical propagation delays of 400–775 ps depending on temperature.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix DTG corresponds to the TSSOP-20 package with 75 units per rail. Confirm RoHS compliance and lead-free status via the manufacturer's documentation. Ensure moisture sensitivity level (MSL) is Level 1 for indefinite time out of drypack. Check for specific date code requirements if applicable to the project timeline.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a three-state PFD with reduced dead zone is required for high-speed PLL designs. Ensure input edge rates are less than 5 ns for proper operation. Verify that the supply voltage matches either PECL (3.0 V–5.5 V) or NECL (-3.0 V to -5.5 V) configurations. Consider thermal management as power supply current can reach up to 170 mA at elevated temperatures.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The MC100EP40 belongs to the 100EP series from onsemi, which contains temperature-compensated ECL logic devices. This series is optimized for high-speed digital applications requiring differential signaling. The DTG suffix indicates a Pb-Free package in a TSSOP-20 form factor, suitable for surface-mount assembly.
