SY100EP33VZG-TR

Overview

The SY100EP33VZG-TR is a ÷4 PECL/LVPECL divider from the Precision Edge ECL Pro series. It operates at guaranteed maximum frequencies exceeding 4GHz with propagation delays under 460ps across the industrial temperature range of −40°C to +85°C. The device supports 3.3V and 5V power supply options, features internal 75kΩ input pull-down resistors, and includes an asynchronous reset pin for synchronous system use. It is housed in an 8-pin SOIC package.

Feature Summary

• Integrated divide-by-four frequency division functionality
• Internal reference voltage generation via VBB pin
• Asynchronous reset capability for synchronized multi-device systems

Applications

• High-speed clock distribution networks
• Frequency synthesis circuits
• Telecommunications infrastructure timing

Procurement Notes

Verify component authenticity through authorized Microchip Technology channels or certified distributors. Confirm that the ordering suffix matches the required tape and reel packaging format. Ensure compliance with RoHS directives and lead-free specifications as indicated by the 'G' suffix. Validate that the industrial temperature rating aligns with operational environmental requirements before finalizing procurement.

Selection Notes

Select this component when precise divide-by-four frequency scaling is required for high-speed differential signaling applications. Consider the availability of the internal VBB pin for AC-coupled input rebiasing if single-ended inputs are utilized. Evaluate the asynchronous reset feature against system synchronization needs. Verify compatibility with existing 3.3V or 5V power supply architectures within the target design constraints.

FAQ

How should the unused differential input be handled during single-ended operation?

Connect the unused differential input to the VBB pin, which serves as an internally-generated switching reference voltage.

What is the function of the VBB pin?

The VBB pin provides an internally-generated reference voltage output that can be used to rebias AC-coupled inputs or serve as a reference for single-ended conditions.
