SY100EL33LZG-TR

Counter Dividers Overview

The SY100EL33LZG-TR is a 3.3V ECL ÷4 divider integrated circuit manufactured by Microchip Technology. It operates within a supply voltage 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 utilizes an asynchronous reset mechanism and includes internal 75 kΩ input pull-down resistors. The component is housed in an 8-pin SOIC package and functions across an industrial temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Supports differential, single-ended, or AC-coupled interfaces via dedicated clock inputs and VBB bias pin
• Provides an asynchronous reset function for system synchronization upon power-up
• Integrates internal 75 kΩ input pull-down resistors to stabilize logic states

Counter Dividers Applications

• High-speed clock frequency division in digital systems
• Synchronization of multiple divider circuits using the asynchronous reset feature
• Integration into PECL or NECL based signal processing architectures

Counter Dividers Procurement Notes

Verify that the specific ordering suffix matches the required packaging configuration, as the standard tube variant differs from the tape and reel option. Confirm the lead finish specifications align with assembly requirements. Ensure the selected part number corresponds to the correct temperature grade and package outline dimensions before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a precise divide-by-four ratio is required for high-frequency clock signals. The device accommodates both PECL and NECL logic families through appropriate power supply configurations. Designers must account for the VBB output's limited current capability if utilizing it for external biasing applications.

Counter Dividers Part Context

This device belongs to the SY100EL33L family of 3.3V ECL dividers. It serves as a core timing element for generating lower frequency clocks from higher frequency sources. The product line emphasizes high bandwidth transitions and low propagation delays suitable for demanding communication and computing infrastructure.
