MC10EL32DG

Counter Dividers Overview

The MC10EL32DG is a 5V ECL ÷2 divider manufactured by onsemi, housed in an SOIC-8NB package. It supports PECL mode with VCC ranging from 4.2 V to 5.7 V (VEE = 0 V) and NECL mode with VEE ranging from -4.2 V to -5.7 V (VCC = 0 V). The device features a propagation delay of 510 ps and a maximum toggle frequency of 3.0 GHz. It includes an internal reference voltage (VBB) for single-ended or AC-coupled interfaces, asynchronous reset functionality, and internal input pulldown resistors.

Counter Dividers Feature Summary

• Supports differential, single-ended, and AC-coupled clock inputs via the integrated VBB pin.
• Provides asynchronous reset capability for system synchronization upon power-up.
• Includes internal input pulldown resistors on clock and reset lines to stabilize signals.
• Offers robust electrostatic discharge protection exceeding standard human body and machine models.

Counter Dividers Applications

• Clock signal division in high-speed digital systems
• Frequency synthesis circuits requiring precise timing
• Synchronization of multiple logic devices within a system

Counter Dividers Procurement Notes

Verify that the specific part number matches the required logic family and package type. Confirm that the design environment accommodates the specified operating temperature range and supply voltage requirements. Ensure proper termination techniques are applied to outputs to maintain signal integrity according to ECL standards.

Counter Dividers Selection Notes

Select this component when a divide-by-two function is required for ECL-based architectures. Consider the MC100EL32 variant if temperature compensation is necessary for the application environment. Verify compatibility with existing PECL or NECL power supplies before integration into the circuit design.

Counter Dividers FAQ

How should the VBB pin be handled if single-ended input is not used?

If the VBB pin is not utilized for single-ended or AC-coupled inputs, it should be left open.

What is the behavior of the internal flip-flop upon power-up?

Upon power-up, the internal flip-flop attains a random state until the asynchronous reset pin is asserted.
