SY100EL33ZI-TR

Overview

The SY100EL33ZI-TR is a 3.3V ECL ÷4 divider integrated circuit manufactured by Microchip Technology. It operates within a power supply range of 3.0V to 3.8V and supports toggle frequencies up to 4.2 GHz. The device features a typical propagation delay of 640ps from clock input to output and 460ps from reset to output. It includes internal 75 kΩ input pull-down resistors and an asynchronous reset pin for system synchronization. The component is housed in an 8-pin SOIC package.

Feature Summary

• Integrated ÷4 divider with differential, single-ended, or AC-coupled interface options
• Asynchronous reset pin allows for the synchronization of multiple dividers in a system
• Internal 75 kΩ input pull-down resistors simplify circuit design
• Output reference voltage (VBB) available for input biasing

Applications

• Clock distribution networks requiring frequency division
• High-speed digital systems utilizing PECL or NECL logic levels
• Synchronization circuits for multi-chip modules

Procurement Notes

Verify that the specific ordering suffix matches the required tape and reel packaging configuration. Confirm the lead-free status and industrial temperature range specifications align with your assembly process requirements. Ensure compatibility with standard surface mount reflow profiles for the 8-pin SOIC package before finalizing procurement orders.

Selection Notes

Select this component when a high-speed divide-by-four function is required for 3.3V ECL applications. Consider the 4.2 GHz toggle frequency limit and propagation delay characteristics against your system timing constraints. Evaluate the need for the asynchronous reset feature if synchronized startup across multiple devices is necessary for your specific design architecture.

Part Context

This part belongs to the SY10/100EL series of high-speed ECL logic devices produced by Microchip Technology. The series encompasses various dividers, receivers, and translators designed for precision edge applications. The SY100EL33L variant specifically addresses the need for compact, low-power frequency division in dense electronic systems operating at gigahertz speeds.
