SY100EL33ZG-TR

Overview

The SY100EL33ZG-TR is a 3.3V ECL ÷4 divider 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 operates on a PECL supply voltage of 3.0V to 3.8V or NECL supply voltage of -3.8V to -3.0V. It includes internal 75 kΩ input pull-down resistors and provides differential, single-ended, or AC-coupled interface options via dedicated clock inputs and a VBB reference output.

Feature Summary

• Integrated divide-by-four functionality for high-speed clock signal processing
• Supports differential, single-ended, and AC-coupled input interfaces
• Includes asynchronous reset pin for system synchronization

Applications

• High-speed clock distribution networks
• Frequency division in telecommunications systems
• Synchronization circuits requiring precise timing control

Procurement Notes

Verify the specific ordering suffix 'ZG' corresponds to the 8-Lead SOIC package and lead-free NiPdAu finish as documented in the product identification system. Confirm that the '-TR' suffix indicates tape and reel packaging containing 1,000 units per reel. Ensure compatibility with standard SMD/SMT assembly processes and check for RoHS compliance documentation prior to final procurement.

Selection Notes

Select this component when a low-power, high-speed divide-by-four function is required within the ECL logic family. The device supports both PECL and NECL power supply configurations, offering flexibility in system design. Consider the 8-Lead SOIC package constraints and the need for proper termination through a 50 Ω resistor to VCC – 2.0V for optimal AC performance.

Part Context

This part belongs to the SY100EL33L series, which are integrated dividers designed for 3.3V operation. The series is characterized by high bandwidth output transitions and internal pull-down resistors. The ZG suffix denotes the specific package type and environmental rating, while TR specifies the bulk packaging format for automated manufacturing.
