SY10EP33VKI

Overview

The SY10EP33VKI is a ÷4 divider from the 10EP series, manufactured by Microchip Technology. It supports PECL and LVPECL logic families with 3.3V and 5V power supply options. The device guarantees a maximum frequency exceeding 4GHz and propagation delay under 460ps across the operating temperature range of -40°C to +85°C. It features an asynchronous reset pin for synchronous system use and includes internal 75kΩ input pull-down resistors. The component is housed in an 8-pin MSOP package.

Feature Summary

• Integrated divide-by-4 divider function supporting high-frequency clock distribution
• Asynchronous reset pin enables synchronized operation of multiple devices within a system
• Internal reference voltage (VBB) available for single-ended inputs or AC-coupled input rebiasing
• Includes internal temperature compensation circuitry for stable performance

Applications

• High-speed clock signal division
• Clock distribution networks requiring precise timing
• Synchronization of multiple divider stages in complex systems

Procurement Notes

Verify that the specific part number matches the required industrial temperature range (-40°C to +85°C). Confirm the 8-pin MSOP package type aligns with your PCB footprint requirements. Ensure compatibility with PECL/LVPECL logic levels and power supply voltages before integration into the design.

Selection Notes

Select this component when a guaranteed maximum frequency above 4GHz is required for clock division applications. Consider the availability of the internal VBB pin if single-ended inputs or AC coupling rebiasing are necessary. Verify that the asynchronous reset functionality meets the synchronization needs of the broader system architecture.

Part Context

This component belongs to the 10EP series of high-speed dividers originally developed by Micrel, Inc., which was later acquired by Microchip Technology. The '10' prefix denotes the specific family characteristics, while 'EP' indicates the Precision Edge technology used for low jitter and high-speed performance. The 'VKI' suffix specifies the 8-pin MSOP package and industrial temperature rating.
