SY100EL91ZC

Translators, Level Shifters Overview

The SY100EL91ZC is a triple PECL-to-ECL translator manufactured by Microchip Technology. It operates with a VCC supply of 4.75V to 5.25V and a VEE supply of -4.2V to -5.5V. The device features a typical propagation delay of 620ps for differential inputs and 620ps for single-ended inputs. It supports a minimum input swing of 200mV and provides an internal reference voltage output (PECL_VBB) for interfacing with single-ended signals. The component is housed in a 20-pin wide SOIC package.

Translators, Level Shifters Feature Summary

• Translates standard voltage PECL signals to ECL outputs
• Includes a dedicated PECL reference voltage output for single-ended input compatibility
• Utilizes a fully differential design architecture

Translators, Level Shifters Applications

• Interfacing between PECL and ECL logic families
• Voltage level translation in high-speed digital circuits
• Systems requiring conversion from single-ended PECL inputs to differential ECL outputs

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'ZC' against current manufacturer documentation, as it indicates commercial temperature range and Sn-Pb lead finish. Confirm availability status, as this part may be discontinued or restricted. Ensure compliance with RoHS directives if Pb-free variants are required for modern manufacturing processes.

Translators, Level Shifters Selection Notes

Select this component when translating PECL signals to ECL levels within a 5V system. Ensure the design accommodates three distinct power rails: VCC, VEE, and GND. Verify that the application requires the specific 20-pin SOIC footprint and that the operating temperature range aligns with commercial specifications.

Translators, Level Shifters Part Context

This component belongs to the SY100EL91 series of translators. It is designed for applications requiring reliable signal conversion between different emitter-coupled logic standards. The device integrates necessary biasing and reference generation internally to simplify circuit design.

Translators, Level Shifters Replacement Considerations

Consult official datasheets for direct pin-compatible alternatives such as the SY100EL91ZI for industrial temperature ranges or the SY100EL91ZG for Pb-free packaging options.
