MC100EP33DTG

Counter Dividers Overview

The MC100EP33DTG is a divide-by-4 ECL divider manufactured by onsemi, housed in an 8-lead TSSOP package. It operates with differential clock inputs and 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). The device features a typical propagation delay of 320 ps and a maximum frequency exceeding 4 GHz. It includes an asynchronous reset pin for synchronization and an internally generated VBB reference voltage output.

Counter Dividers Feature Summary

• Differential clock inputs enable high-speed signal processing with low noise characteristics.
• Asynchronous reset functionality allows for system synchronization across multiple devices.
• Internal VBB reference voltage provides switching references and AC coupling bias capabilities.

Counter Dividers Applications

• High-frequency clock distribution networks
• System synchronization circuits requiring precise timing alignment
• Buffering applications for ultra-high-speed oscillators

Counter Dividers Procurement Notes

Verify the specific ordering suffix DTG confirms the TSSOP-8 package configuration. Confirm RoHS compliance status as required by project specifications. Check current availability status as some variants may be discontinued or not recommended for new designs. Ensure thermal management requirements are met for the selected operating environment.

Counter Dividers Selection Notes

Select this component when a divide-by-4 function is required within ECL logic families. Consider the TSSOP-8 package for surface-mount assembly constraints. Evaluate power supply compatibility with PECL or NECL standards based on system voltage rails. Verify that the 320 ps propagation delay meets the timing budget of the target application.

Counter Dividers Part Context

This part belongs to the MC10/100EP33 series of integrated dividers from onsemi. The 100 Series designation indicates temperature compensation features for stable performance across varying environmental conditions. It shares functional similarities with other EP family members but offers specific divide-by-4 architecture optimized for high-frequency operations.

Counter Dividers Replacement Considerations

MC10EP33DTG serves as a direct equivalent variant within the same product family.

Counter Dividers FAQ

How should the VBB pin be handled if single-ended inputs are used?

Connect the unused differential input to the VBB pin to serve as a switching reference voltage. Decouple VBB and VCC using a 0.01 µF capacitor and limit current sourcing or sinking to 0.5 mA.

What is the behavior of the Q output when inputs are left open?

The Q output will default to a LOW state when the inputs are open or at VEE, ensuring a defined logic level during undefined input conditions.
