SY10EP32VKI-TR

Overview

The SY10EP32VKI-TR is a ÷2 divider with differential clock inputs, operating on 3.3V or 5V supplies. It guarantees a maximum frequency exceeding 4 GHz and propagation delay under 440 ps across the –40°C to +85°C range. The device features an asynchronous reset pin, open input default state, and internal temperature compensation. It is housed in an 8-lead MSOP package.

Feature Summary

• Integrated divide-by-two divider with differential clock inputs
• Asynchronous reset pin for synchronous system use
• Internal VBB reference voltage output for single-ended input biasing
• Open input default state with internal pull-down resistors

Applications

• High-speed clock distribution networks
• Frequency division in precision timing systems
• Synchronization of multiple divider stages

Procurement Notes

Verify the exact ordering suffix against official Microchip documentation to confirm the specific tape-and-reel packaging configuration. Confirm that the component meets RoHS compliance requirements for your target assembly process. Ensure compatibility with standard surface-mount reflow soldering profiles specified for the 8-lead MSOP package.

Selection Notes

Select this component when a high-frequency divide-by-two function is required within a differential ECL architecture. Consider the guaranteed propagation delay and jitter specifications for precise timing applications. Evaluate the power supply options to match existing 3.3V or 5V system rails efficiently.

Part Context

This part belongs to the SY10/100EP series of Precision Edge dividers from Microchip Technology. It is designed for high-performance clock management applications requiring reliable frequency division at multi-gigahertz speeds. The device integrates internal circuitry to simplify interface design for differential clock signals.

Replacement Considerations

Public confirmed substitute: MC100EP31DTG (onsemi). Verify functional equivalence and pinout compatibility before substitution.

FAQ

How should the VBB pin be handled if not used?

When the VBB pin is not utilized for input biasing, it should be left open.

What is the behavior of the outputs under open input conditions?

Under open input conditions, the CLK input and reset input are pulled to GND, while the /CLK input is biased at half of the supply voltage.
