SY100EP32VKI-TR

Overview

The SY100EP32VKI-TR is a 5V/3.3V ECL ÷2 divider manufactured by Microchip Technology, housed in an 8-Lead MSOP package with tape and reel processing. It supports PECL (VCC = 3.0V to 5.5V) and NECL (VEE = –5.5V to –3.0V) power supply options. The device guarantees a maximum toggle frequency of 4 GHz and propagation delay under 440 ps across the operating temperature range of –40°C to +85°C. Cycle-to-cycle RMS jitter is typically 0.2 ps.

Feature Summary

• Integrated divide-by-two functionality with differential clock inputs for precise frequency division.
• Includes an internally generated VBB reference voltage pin to facilitate single-ended input conditions or AC-coupled input rebiasing.
• Features an asynchronous reset pin that allows synchronous operation when multiple devices are used within a system.
• Incorporates internal temperature compensation circuitry to maintain stable performance across varying thermal environments.

Applications

• High-speed clock signal distribution networks
• Frequency synthesis and generation circuits
• Digital communication systems requiring precise timing

Procurement Notes

Verify the specific ordering suffix 'TR' confirms the tape and reel packaging format containing 1,000 units per reel. Confirm the 'K' package designation matches the required 8-Lead MSOP footprint. Ensure the 'G' temperature grade aligns with the specified industrial range of –40°C to +85°C. Cross-reference the datasheet revision history to confirm compatibility with current design specifications.

Selection Notes

Select this component when a high-frequency divide-by-two function is required for ECL-based logic families. The device accommodates both 3.3V and 5V supply rails, offering flexibility for mixed-voltage designs. Consider the low propagation delay and minimal jitter characteristics for applications demanding tight timing margins. Evaluate the MSOP package size against available board space constraints.

Part Context

This part belongs to the SY100EP series of ECL Pro components designed for high-performance digital applications. The SY100EP32V variant specifically provides a divide-by-two function, distinguishing it from buffer or driver counterparts within the same family. It represents a transition from legacy Micrel products now managed under Microchip Technology's portfolio.
