SY100EP33VKG

Overview

The SY100EP33VKG is an integrated divide-by-4 clock divider manufactured by Microchip Technology. It operates with differential ECL inputs and supports both 3.3V and 5V power supply options. The device guarantees a maximum toggle frequency exceeding 4 GHz, with propagation delay from CLK to Q remaining under 460 ps across the operating temperature range of -40°C to +85°C. It features an asynchronous reset pin asserted on the rising edge, allowing for synchronous system use. An internal VBB reference voltage is available for single-ended input biasing or AC-coupled input rebiasing. The component is housed in an 8-lead MSOP package.

Feature Summary

• Integrated divide-by-4 functionality with differential clock inputs
• Internal VBB reference voltage for input biasing and AC coupling
• Asynchronous reset capability for synchronized multi-device systems
• Temperature-compensated circuitry ensuring stable operation

Applications

• High-speed clock signal division
• Differential clock distribution networks
• PECL/LVPECL logic interface circuits
• Precision timing and synchronization systems

Procurement Notes

Verify the specific ordering suffix 'KG' confirms the 8-lead MSOP package configuration and lead finish specifications. Confirm the absence of the '-TR' suffix indicates tube packaging rather than tape and reel. Ensure the procurement documentation explicitly states compliance with RoHS directives and identifies the correct moisture sensitivity level for storage and handling requirements.

Selection Notes

Select this component when a high-frequency divide-by-4 function is required within PECL or LVPECL architectures. It is suitable for designs needing guaranteed performance above 4 GHz with low propagation delay. Consider the availability of the internal VBB pin if single-ended conversion or AC coupling biasing is necessary without external components. Verify that the 8-lead MSOP footprint aligns with the target PCB layout constraints.

Part Context

This part belongs to the SY100/10EP series of ECL dividers and buffers produced by Microchip Technology. It serves as a successor to earlier Micrel products within the same functional family. The device is designed for applications requiring precise frequency division and robust signal integrity at high speeds. It complements other clock management solutions in the manufacturer's portfolio.
