SY10EL33LZG

Overview

The SY10EL33LZG is a 3.3V ECL ÷4 divider manufactured by Microchip Technology in an 8-lead SOIC package. It operates with a power supply voltage of 3.0V to 3.8V and supports toggle frequencies up to 4.2 GHz. The device features a typical propagation delay of 640ps and includes internal 75 kΩ input pull-down resistors. It provides differential, single-ended, or AC-coupled interfaces via CLK, /CLK inputs and VBB reference output. An asynchronous reset pin allows for system synchronization.

Feature Summary

• Integrated ÷4 divider functionality with differential clock inputs
• Asynchronous reset capability for system synchronization
• Internal 75 kΩ input pull-down resistors
• Supports differential, single-ended, or AC-coupled interfaces

Applications

• Clock distribution networks requiring frequency division
• High-speed digital systems utilizing PECL/NECL signaling
• Synchronization circuits for multiple divider stages

Procurement Notes

Verify the specific ordering suffix 'ZG' corresponds to the 8-Lead SOIC package with industrial temperature range (-40°C to +85°C) and Pb-Free NiPdAu finish as defined in the product identification system. Confirm that the required quantity matches the standard tube packaging configuration (95 units per tube) unless tape and reel options are explicitly requested from the manufacturer.

Selection Notes

Select this component when a fixed ÷4 division ratio is required for high-frequency clock signals up to 4.2 GHz. Ensure the design accommodates the 3.3V power supply requirements and utilizes the VBB output for proper biasing if single-ended or AC-coupled inputs are employed. Consider the 8-pin SOIC footprint during PCB layout.

Part Context

This device belongs to the Precision Edge SY100EL33L family of integrated dividers designed for high-speed ECL applications. It serves as a successor to earlier versions like the SY10EL33, offering updated specifications and packaging options while maintaining compatibility with standard ECL logic levels and interface requirements.
