SY100E116JY-TR

Specialty Logic Overview

The SY100E116JY-TR is a quint differential line receiver manufactured by Microchip Technology, housed in a 28-pin PLCC package. It operates within an extended VEE range of –4.2V to –5.5V and features emitter-follower outputs with an internally generated VBB reference supply for single-ended reception. The device provides a maximum propagation delay of 450ps at +85°C and includes internal 75KΩ input pulldown resistors. It is fully compatible with industry standard 10KH and 100K I/O levels.

Specialty Logic Feature Summary

• Features clamp circuitry that forces a defined output state when both differential inputs are left open.
• Utilizes active current sources combined with ASSET technology to provide excellent common mode noise rejection.
• Includes an internally generated VBB reference voltage output specifically designed for single-ended ECL signal reception.

Specialty Logic Applications

• High-performance ECL systems
• Single-ended reception of ECL signals
• Differential signal transmission interfaces

Specialty Logic Procurement Notes

Verify the component status as the datasheet indicates it is not recommended for new designs. Confirm the specific ordering suffix matches the required tape and reel packaging and lead-free finish specifications. Ensure compatibility with existing system power supplies and logic levels before procurement.

Specialty Logic Selection Notes

Select this component for applications requiring high-speed differential signal reception within ECL architectures. Consider the 450ps propagation delay limit and the requirement for a negative power supply rail between –4.2V and –5.5V. Evaluate the need for the integrated VBB reference if single-ended conversion is necessary.

Specialty Logic Part Context

This part belongs to the SY10/100E116 family of quint differential line receivers originally developed by Micrel, Inc., which was subsequently acquired by Microchip Technology. The series is designed to interface with industry-standard logic families while maintaining high-speed performance characteristics suitable for complex digital communication systems.

Specialty Logic Replacement Considerations

The datasheet explicitly states full compatibility with the Motorola MC10E/100E116. Verify pinout and electrical parameter alignment when substituting with equivalent parts from other manufacturers.

Specialty Logic FAQ

What happens if both the inverting and non-inverting inputs are left open?

The receiver design features clamp circuitry that causes a defined output state where the Q output goes LOW and the Q-bar output goes HIGH.

How should the VBB output be handled for single-ended reception?

It is recommended that VBB is decoupled to VCC via a 0.01 µF capacitor when used as a reference voltage for single-ended reception.
