SY10EP33VZI-TR

Overview

The SY10EP33VZI-TR is a ÷4 PECL/LVPECL divider from the Precision Edge® 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 both 3.3V and 5V power supply options and includes an internal VBB reference voltage pin for AC-coupled input rebiasing or single-ended switching references. An asynchronous reset pin ensures synchronous system operation upon power-up.

Feature Summary

• Integrated divide-by-four frequency division functionality
• Internal VBB reference voltage output for input biasing
• Asynchronous reset capability for synchronized multi-device systems
• Internal temperature compensation circuitry

Applications

• High-speed clock distribution networks
• Frequency synthesis and generation circuits
• Telecommunications infrastructure equipment
• Test and measurement instrumentation

Procurement Notes

Verify that the ordering suffix 'TR' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the specific package variant matches the design footprint, as the device is available in MSOP and SOIC configurations. Ensure the industrial temperature rating aligns with the operational environment requirements before finalizing procurement.

Selection Notes

Select this component when a high-frequency divide-by-four function is required within PECL or LVPECL logic families. The inclusion of an internal VBB pin simplifies designs requiring AC-coupled inputs by providing a dedicated reference voltage source. Consider the asynchronous reset feature if multiple dividers must be synchronized during system initialization.

Part Context

This part belongs to the SY10/100EP33V family manufactured originally by Micrel, Inc., which was subsequently acquired by Microchip Technology. The Precision Edge® branding denotes high-performance ECL Pro™ technology designed for demanding RF and microwave applications requiring precise timing and low jitter characteristics.

FAQ

How should the VBB pin be handled if not used?

When the VBB pin is not utilized for AC-coupled input rebiasing or single-ended switching references, it should be left open.

What is the function of the RESET pin?

The RESET pin is asynchronous and is asserted on the rising edge, allowing for the synchronous use of multiple EP33 devices in a system despite random flip-flop states upon power-up.
