SY100EL16VOKI

Specialty Logic Overview

The SY100EL16VOKI is a precision PECL amplifier manufactured by Microchip Technology, housed in a 10-pin MSOP package. It supports 3.3V and 5V ±10% power supply options with an operating temperature range of –40°C to +85°C. The device features a maximum frequency (fMAX) of 800MHz, propagation delays of 200ps for the QFB outputs and 650ps for the QHG outputs, and a cycle-to-cycle jitter of 0.2ps RMS. It includes an enable pin (/EN) for output control and a VBB reference voltage.

Specialty Logic Feature Summary

• Supports both 3.3V and 5V nominal supply voltages with guaranteed AC parameters over the full industrial temperature range.
• Features dual differential outputs: a fast QFB path and a high-gain QHG path suitable for low-input swing applications.
• Includes an active-low enable pin (/EN) that forces the differential outputs into a fixed logic state when deactivated.
• Provides an integrated VBB reference voltage to facilitate single-ended or AC-coupled circuit configurations.

Specialty Logic Applications

• High-speed clock distribution networks requiring precise timing and low jitter.
• Differential signaling interfaces utilizing PECL or LVPECL logic standards.
• Applications requiring signal amplification from very low input swings via the high-gain QHG outputs.
• Systems needing controlled output states through the dedicated enable pin functionality.

Specialty Logic Procurement Notes

Verify the specific ordering suffix 'KI' confirms the Industrial temperature grade (-40°C to +85°C) and Sn-Pb lead finish as documented in the manufacturer's ordering information. Confirm the K10-1 package type matches your PCB footprint requirements. Ensure design compatibility with the specified DC electrical characteristics for your chosen supply voltage configuration.

Specialty Logic Selection Notes

Select this component when a high-frequency PECL amplifier with distinct fast and high-gain output paths is required. The inclusion of an enable pin allows for dynamic power management or signal gating without external logic. Verify that the 10-pin MSOP package fits within the available board space constraints and thermal dissipation limits for the intended application environment.

Specialty Logic Part Context

This part belongs to the SY100EL series of precision ECL/PECL amplifiers designed for high-speed digital communication systems. Manufactured originally by Micrel, Inc., it is now part of the Microchip Technology portfolio. The device is engineered to maintain performance stability across varying supply voltages and temperatures, making it suitable for robust industrial and commercial electronic designs.

Specialty Logic Replacement Considerations

Check for equivalent parts such as the SY100EL16VO variants with different packaging or lead finishes. Verify functional compatibility regarding pinout, supply voltage ranges, and electrical specifications before substitution.

Specialty Logic FAQ

What is the difference between the QFB and QHG outputs?

The QFB outputs provide a faster propagation delay of 200ps, while the QHG outputs offer higher DC gain (200 or higher) to handle minimum input swings as low as 150mV, albeit with a longer delay of 650ps.

How does the /EN pin function?

The /EN pin is an active-low enable input. When asserted, it forces the differential outputs into a fixed logic state, effectively disabling the normal signal transmission.
