SY100EL33ZI

Overview

The SY100EL33ZI is a 3.3V ECL ÷4 divider integrated circuit manufactured by Microchip Technology, housed in an 8-lead SOIC package with industrial temperature range (-40°C to +85°C). It features a typical propagation delay of 640ps and a maximum toggle frequency of 4.2 GHz. The device supports differential, single-ended, or AC-coupled clock inputs via CLK and /CLK pins. An internal VBB reference voltage output provides biasing for input stages. The asynchronous Reset pin allows synchronization of multiple dividers upon power-up.

Feature Summary

• Integrated ÷4 divider functionality supporting high-speed clock signal division
• Supports differential, single-ended, and AC-coupled interface configurations
• Includes internal 75 kΩ input pull-down resistors and VBB reference voltage output

Applications

• High-speed clock distribution networks
• Frequency division in ECL logic systems
• Synchronization of multiple divider circuits using the asynchronous reset feature

Procurement Notes

Verify that the ordering suffix 'Z' corresponds to the 8-lead SOIC package and 'G' indicates the industrial temperature range (-40°C to +85°C) with lead-free NiPdAu finish. Confirm whether the specific part number includes tape-and-reel processing or tube packaging, as this affects handling and storage requirements during assembly.

Selection Notes

Select this component when a precise ÷4 division ratio is required for 3.3V ECL applications. Ensure the system design accommodates the specified 4.2 GHz toggle frequency limit and the 640ps typical propagation delay. Verify compatibility with the available differential or single-ended input swing requirements defined in the electrical characteristics.

Part Context

This device belongs to the SY100EL33L family of 3.3V ECL dividers. It is designed for use in high-performance digital systems requiring reliable frequency division. The product line emphasizes low propagation delay and high bandwidth output transitions suitable for demanding timing applications.

Replacement Considerations

SY100EL33LZG is a confirmed equivalent part within the same series offering identical electrical specifications and functionality.
