SY100EL33ZC-TR

Overview

The SY100EL33ZC-TR is a 3.3V ECL ÷4 divider manufactured by Microchip Technology, housed in an 8-pin SOIC package. It operates within a temperature range of -40°C to +85°C and features a typical toggle frequency of 4.2 GHz with a propagation delay of 640 ps. The device supports differential, single-ended, or AC-coupled clock inputs via CLK and /CLK pins. An internal VBB output provides reference voltage biasing for the EL33L, requiring a 0.01µF bypass capacitor to ground. Asynchronous reset functionality synchronizes multiple dividers upon power-up.

Feature Summary

• Integrated divide-by-four logic function designed for high-speed clock signal processing
• Supports flexible interface configurations including differential, single-ended, and AC-coupled connections
• Includes asynchronous reset capability for system synchronization and state control

Applications

• High-frequency clock distribution networks
• Differential clock signal generation systems

Procurement Notes

Verify that the component matches the specific 8-pin SOIC package configuration and lead-free NiPdAu finish requirements. Confirm the industrial temperature rating aligns with operational environmental constraints. Ensure the ordering suffix corresponds to the tape and reel packaging format rather than tube packaging. Cross-reference the manufacturer part number against current datasheet revisions to validate functional specifications.

Selection Notes

Select this component when a precise divide-by-four ratio is required for 3.3V ECL or PECL applications. Consider the 4.2 GHz toggle frequency limit and 640 ps propagation delay for timing-sensitive designs. Evaluate the need for the integrated VBB reference output to simplify external biasing circuitry. Assess the asynchronous reset feature for managing startup states in complex multi-device systems.
