SY100EL91ZG

Translators, Level Shifters Overview

The SY100EL91ZG 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, with a maximum of 800ps for single-ended inputs. It utilizes a 20-pin SOIC package and supports an operating temperature range from -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Translates standard voltage PECL signals to different ECL output signals
• Includes a dedicated PECL reference voltage output for interfacing with single-ended inputs
• Ensures stability under open input conditions by biasing the D input at VCC/2

Translators, Level Shifters Applications

• Interfacing between PECL and ECL logic families
• Voltage level translation in high-speed digital systems
• Single-ended PECL signal conversion using the VBB reference pin

Translators, Level Shifters Procurement Notes

Verify component authenticity through authorized channels as this part may be discontinued or subject to limited availability. Confirm that the specific ZG suffix corresponds to the lead-free NiPdAu finish variant required for your assembly process. Ensure compatibility with existing PCB footprints for the 20-pin wide SOIC package before finalizing procurement plans.

Translators, Level Shifters Selection Notes

Select this component when translating PECL signals to ECL levels is required within a system. Consider the 20-pin SOIC package constraints and the need for three distinct power rails (VCC, VEE, GND). Evaluate the 620ps typical propagation delay against system timing requirements to ensure signal integrity is maintained across the translation interface.

Translators, Level Shifters Part Context

This device belongs to the SY100EL series of logic translators produced by Micrel, now part of Microchip Technology. It is designed for applications requiring reliable voltage level shifting between PECL and ECL standards. The ZG suffix indicates a lead-free package with a NiPdAu bar-line indicator, suitable for industrial temperature ranges.

Translators, Level Shifters Replacement Considerations

Check for direct replacements within the SY100EL family. Verify if alternative packages or lead finishes are available from the manufacturer. Consult official documentation for any updated versions or cross-references provided by Microchip Technology.
