MC100EP32MNR4G

Counter Dividers Overview

The MC100EP32MNR4G is a divide-by-2 ECL/CML divider manufactured by onsemi, housed in an 8-lead DFN package. It features differential CLK inputs and an asynchronous reset pin that asserts on the rising edge. The device supports PECL mode with VCC ranging from 3.0 V to 5.5 V (VEE = 0 V) and NECL mode with VEE ranging from -3.0 V to -5.5 V (VCC = 0 V). It includes an internally generated VBB reference voltage for single-ended input biasing or AC coupling rebiasing. The component operates within a temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Differential clock inputs with an asynchronous reset function for system synchronization
• Integrated VBB reference voltage output for single-ended input configuration and AC coupling
• Temperature compensation included within the 100 Series architecture
• Safety clamps on inputs to protect against overvoltage conditions

Counter Dividers Applications

• High-speed clock distribution networks requiring frequency division
• System synchronization circuits utilizing asynchronous reset capabilities
• PECL and NECL logic interface applications
• Biasing and reference generation for differential-to-single-ended conversion

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'MNR4G' corresponds to the DFN-8 package and tape-and-reel shipping format. Confirm RoHS compliance status as indicated in the datasheet attributes. Ensure the procurement documentation matches the manufacturer's current product availability guidelines, noting potential discontinuation statuses for related variants in the same family.

Counter Dividers Selection Notes

Select this component when a divide-by-2 function with differential inputs is required in high-speed digital systems. Consider the DFN-8 package for space-constrained designs. Verify power supply requirements align with either PECL or NECL operating ranges. Evaluate the need for the internal VBB reference if single-ended inputs are utilized in the design.

Counter Dividers Part Context

This part belongs to the MC10/100EP32 series of integrated dividers. The 100 Series variant specifically incorporates temperature compensation. It shares functional similarities with other ECL logic devices but is distinct in its dedicated divide-by-2 topology and integrated reference voltage provision.

Counter Dividers Replacement Considerations

Consult the datasheet ordering information for alternative packages such as SOIC-8NB or TSSOP-8. Verify compatibility with existing board layouts due to package dimension differences between DFN and other form factors.

Counter Dividers FAQ

How should the VBB pin be handled if single-ended inputs are not used?

If the VBB pin is not utilized for biasing or AC coupling, it should be left open.

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.
