MC100EP32DR2

Counter Dividers Overview

The MC100EP32DR2G is a surface-mount integrated ÷2 divider from the onsemi MC100EP series, housed in an SOIC-8NB package. It features differential CLK inputs and asynchronous reset functionality asserted 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). Key electrical parameters include a typical propagation delay of 350 ps and a maximum toggle frequency exceeding 4 GHz.

Counter Dividers Feature Summary

• Differential clock input architecture with dedicated VBB reference voltage pin for single-ended or AC-coupled interface flexibility
• Asynchronous reset capability allowing system synchronization across multiple devices upon power-up
• Temperature compensation circuitry within the 100 Series ensuring stable performance across operating conditions
• Inherent safety clamps and open-input default states that force outputs LOW when inputs are floating

Counter Dividers Applications

• High-speed clock distribution networks requiring precise frequency division
• Synchronization circuits for multi-device systems utilizing asynchronous reset signals
• PECL and NECL logic interfacing in telecommunications infrastructure
• Data processing systems demanding low jitter and high-frequency signal integrity

Counter Dividers Procurement Notes

Verify the complete ordering part number includes the 'G' suffix for RoHS compliance, as indicated by the datasheet ordering information. Confirm the specific package variant matches the required PCB footprint, noting that the DR2G suffix corresponds to tape and reel shipping. Ensure compatibility with existing thermal management strategies, particularly regarding junction-to-ambient resistance values for the SOIC-8NB configuration under specified airflow conditions.

Counter Dividers Selection Notes

Select this component when designing systems requiring a divide-by-two function with differential ECL inputs. The MC100EP32 offers temperature-compensated performance superior to the standard 10EP series. Consider the available packaging options, including tube and tape-and-reel configurations, based on assembly volume requirements. Validate that the chosen supply voltage range aligns with either PECL or NECL operational modes defined in the specifications.

Counter Dividers Part Context

This device belongs to the MC10/100EP family of ECL dividers manufactured by onsemi. The 100 Series designation indicates the inclusion of internal temperature compensation, distinguishing it from the non-compensated 10EP variants. The product line focuses on high-speed digital logic applications where signal integrity and timing precision are critical constraints.

Counter Dividers Replacement Considerations

The MC10EP32 serves as a direct functional equivalent without temperature compensation. For alternative packages, the MC100EP32DTG (TSSOP-8) and MC100EP32MNR4G (DFN-8) provide identical electrical characteristics with different mechanical footprints.
