MC100EL32D

Counter Dividers Overview

The MC100EL32D is a ÷2 divider from the onsemi MC100EL series, 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 maximum toggle frequency of 3.0 GHz and a propagation delay of 510 ps. Power supply current is typically 30 mA. It includes internal input pulldown resistors, asynchronous reset functionality, and temperature compensation.

Counter Dividers Feature Summary

• Supports differential, single-ended, or AC coupled interfaces via dedicated VBB reference voltage pin
• Includes asynchronous reset for system synchronization across multiple devices
• Features temperature compensation for stable performance across operating temperatures
• Provides ESD protection exceeding 1 kV Human Body Model and 100 V Machine Model

Counter Dividers Applications

• Clock signal division and distribution systems
• Frequency synthesis circuits
• High-speed data processing interfaces
• Synchronization of multiple logic components

Counter Dividers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and shipping configuration. The base part number indicates the functional device, but suffixes determine physical attributes such as tape and reel versus tube packaging. Confirm RoHS compliance status and lead times directly with authorized distributors prior to procurement.

Counter Dividers Selection Notes

Select this component when a high-speed ÷2 divider is required for ECL-based architectures. The MC100EL series offers temperature compensation compared to the standard MC10EL series. Ensure the design accommodates the specified power supply ranges for either PECL or NECL operation. Verify that the 510 ps propagation delay meets the timing requirements of the target application.

Counter Dividers Part Context

This device belongs to the MC10EL/100EL family of integrated dividers manufactured by onsemi. It is designed for high-frequency applications requiring precise clock division. The 100 series variant specifically incorporates temperature compensation to enhance stability under varying thermal conditions compared to non-compensated counterparts.

Counter Dividers FAQ

How should the VBB pin be handled if single-ended input is used?

When using single-ended input, connect the unused differential input to the VBB pin to serve as a switching reference voltage. If not used, leave the VBB pin open.

What is the function of the reset pin?

The reset pin is asynchronous and asserted on the rising edge. It allows for the synchronization of multiple EL32 devices within a system upon power-up.
