SY100EL17VZC-TR

Specialty Logic Overview

The SY100EL17VZC-TR is a quad differential receiver manufactured by Microchip Technology, housed in a 20-pin wide SOIC package. It supports both ECL and PECL logic families with supply voltages of -3.3V/-5V or +3.3V/+5V. The device features internal 75KΩ input pull-down resistors and a VBB output for DC biasing. Propagation delay ranges from 280ps to 610ps depending on configuration. Operating temperature spans from -40°C to +85°C.

Specialty Logic Feature Summary

• Quad differential receiver architecture supporting multiple logic standards
• Integrated VBB reference voltage output for AC coupling biasing
• Internal input pull-down resistors ensure stability under open conditions

Specialty Logic Applications

• High-speed data acquisition systems requiring differential signal reception
• Telecommunications equipment utilizing ECL or PECL interfaces
• Test and measurement instruments needing stable high-bandwidth receivers

Specialty Logic Procurement Notes

Verify the specific ordering suffix ZC against current manufacturer documentation to confirm commercial grade status and lead finish specifications. Confirm RoHS compliance requirements as the datasheet indicates Sn-Pb options for this specific suffix. Ensure design-in compatibility with existing PCB footprints for the 20-pin wide SOIC package.

Specialty Logic Selection Notes

Select this component when a quad differential receiver is required for mixed ECL/PECL environments. The integrated VBB pin simplifies biasing networks compared to discrete solutions. Consider the propagation delay characteristics relative to system timing budgets. Verify that the 20-pin wide SOIC package fits within the mechanical constraints of the target enclosure.

Specialty Logic Part Context

This part belongs to the SY100EL series of high-performance ECL devices originally developed by Micrel, now managed by Microchip Technology. The series includes various multiplexers, demultiplexers, and receivers designed for high-speed digital applications. The EL17V specifically addresses the need for robust differential signal reception in legacy and modern high-speed interconnects.

Specialty Logic Replacement Considerations

The datasheet notes functional equivalence to the E116 device. Designers should verify pinout compatibility and electrical parameter overlaps before substituting other quad receivers in the SY100EL family.
