MC100EP32MNR4

Counter Dividers Overview

The MC100EP32MNR4G is a divide-by-2 integrated circuit from the onsemi MC100EP series, housed in an 8-lead DFN package. It features differential CLK inputs and asynchronous reset functionality. The device supports PECL mode (VCC = 3.0 V to 5.5 V) and NECL mode (VEE = -3.0 V to -5.5 V). Key electrical parameters include a typical propagation delay of 350 ps, maximum operating frequency exceeding 4 GHz, and a power supply current of 30 mA at 25°C.

Counter Dividers Feature Summary

• Supports high-speed differential clock division with asynchronous reset for system synchronization
• Includes internally generated VBB reference voltage for single-ended input biasing or AC coupling rebiasing
• Features open input default state where Q output defaults LOW when inputs are open or at VEE
• Incorporates safety clamps on inputs and temperature compensation within the 100 Series

Counter Dividers Applications

• High-frequency clock distribution networks
• Synchronization of multiple divider circuits in complex systems
• PECL/NECL logic interface applications requiring precise timing

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'MNR4G' corresponds to the DFN-8 package configuration. Confirm RoHS compliance status as indicated by the 'G' suffix. Check current availability status, as some devices in this family may be discontinued or not recommended for new designs. Ensure thermal management requirements for the exposed pad are met during integration.

Counter Dividers Selection Notes

Select this component for applications requiring a reliable divide-by-2 function with differential signaling. Consider the DFN-8 package for space-constrained designs requiring efficient thermal dissipation via the exposed pad. Verify compatibility with existing PECL or NECL power supply rails before implementation.

Counter Dividers Part Context

This part belongs to the MC10/100EP32 family of ECL/C00662 dividers manufactured by onsemi. The 100 Series variant includes temperature compensation compared to the standard 10 Series. It is designed for high-performance digital systems utilizing ECL-compatible logic families.

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, which serves as a switching reference voltage. Decouple VBB and VCC with a 0.01uF capacitor and limit current 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 state in the absence of a signal.
