SY10EP32VZG-TR

Overview

The SY100EP32VZG-TR is a 5V/3.3V ECL ÷2 divider manufactured by Microchip Technology, housed in an 8-Lead MSOP package with a –40°C to +85°C operating temperature range. It features a guaranteed maximum toggle frequency exceeding 4 GHz and propagation delay under 440 ps across the full temperature range. The device operates on VCC supplies from 3.0V to 5.5V or VEE supplies from –5.5V to –3.0V, consuming approximately 37 mA of power supply current at room temperature.

Feature Summary

• Integrated divide-by-two functionality with differential clock inputs for high-speed signal processing
• Includes an asynchronous reset pin to allow synchronous use of multiple dividers within a system
• Features an internally generated reference voltage (VBB) available for single-ended input biasing or AC-coupled input rebiasing

Applications

• High-frequency clock distribution networks requiring precise frequency division
• Synchronous digital systems utilizing multiple cascaded ECL dividers
• Differential clock generation circuits in telecommunications infrastructure

Procurement Notes

Verify that the specific ordering suffix matches the required tape and reel packaging configuration. Confirm the exact voltage supply requirements align with your system design before procurement. Ensure proper handling procedures are followed due to moisture sensitivity classification. Cross-reference the manufacturer part number against official datasheets to validate component authenticity and revision status.

Selection Notes

Select this component when a reliable divide-by-two function is required for differential ECL signals up to 4 GHz. Consider the 8-lead MSOP package for space-constrained surface-mount applications. Evaluate the internal VBB pin utility if single-ended inputs or AC coupling is necessary. Verify thermal management capabilities given the junction-to-ambient resistance specifications in still air conditions.

Part Context

This device belongs to the SY100EP series of high-speed ECL logic components designed for demanding data center and communication applications. It serves as a fundamental building block for clock tree architectures where low jitter and precise timing are critical. The product line emphasizes compatibility with both 3.3V and 5V ECL standards to facilitate integration into diverse legacy and modern systems.

FAQ

How should the VBB pin be handled if single-ended inputs are not used?

When not utilized for input biasing or AC coupling, the VBB pin should be left open.

What is the state of the outputs upon initial power-up?

Upon power-up, the internal flip-flops attain a random state until the asynchronous RESET pin is asserted.
