SY100EL17VZC

Specialty Logic Overview

The SY100EL17VZC is a quad differential receiver manufactured by Microchip Technology, housed in a 20-pin wide SOIC package. It supports both ECL and PECL power supply options, operating at -3.3V/-5V or +3.3V/+5V. The device features internal 75KΩ input pull-down resistors and provides a VBB output for DC biasing. Key electrical parameters include a typical propagation delay of 330-360 ps (differential) and a maximum of 530-560 ps across the commercial temperature range (-40°C to +85°C). Power consumption is typically 26 mA.

Specialty Logic Feature Summary

• Quad differential receiver architecture supporting multiple logic families
• Integrated VBB reference voltage output for AC coupling bias
• Internal 75KΩ input pull-down resistors for stability under open conditions

Specialty Logic Applications

• High-speed data transmission systems requiring differential signal reception
• Clock distribution networks utilizing PECL or ECL signaling
• Telecommunications equipment interfacing with legacy ECL components

Specialty Logic Procurement Notes

Verify that the specific suffix ZC corresponds to the commercial temperature grade as defined in the ordering information table. Confirm lead finish specifications match system requirements, noting that Pb-Free variants carry distinct suffixes. Ensure compatibility with existing board layouts designed for the 20-pin wide SOIC footprint before finalizing procurement.

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 circuits compared to receivers lacking this feature. Consider the commercial temperature range limits if operation exceeds standard industrial bounds. Verify that the 75KΩ internal pull-downs meet the impedance requirements of the driving source.

Specialty Logic Part Context

This part belongs to the SY100EL series of high-performance ECL devices originally developed by Micrel, Inc., now managed by Microchip Technology. The series includes various buffers, drivers, and receivers designed for high-speed digital applications. The EL17V specifically addresses the need for multi-channel differential reception in dense packaging configurations.

Specialty Logic Replacement Considerations

The datasheet notes functional equivalence to the E116 device. Cross-reference with other SY100EL series parts for similar channel counts. Verify pinout compatibility when substituting with other quad receivers from the same family.
