SY100EL91ZG-TR

Translators, Level Shifters Overview

The SY100EL91ZG-TR 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 Wide SOIC package (Z20-1) and supports an industrial operating temperature range from -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Translates standard voltage PECL signals to different ECL output signals
• Provides a dedicated PECL reference voltage output for interfacing with single-ended inputs
• Ensures stability under open input conditions through internal biasing

Translators, Level Shifters Applications

• Interfacing between PECL sources and ECL loads in high-speed digital systems
• Level translation in communication networks requiring differential signal conversion
• Clock distribution architectures utilizing mixed logic families

Translators, Level Shifters Procurement Notes

Verify the component status as Not Recommended for New Designs before procurement. Confirm that the ZG suffix corresponds to the lead-free NiPdAu finish variant. Ensure compatibility with existing PCB footprints for the 20-pin Wide SOIC package during sourcing.

Translators, Level Shifters Selection Notes

Select this component when translating three channels of PECL data to ECL levels is required. Verify power supply requirements match the dual rail configuration (+5V and negative voltage). Consider the 20-pin package constraints and thermal management needs for the specified industrial temperature range.

Translators, Level Shifters Part Context

This part belongs to the SY100EL series of high-speed logic devices originally developed by Micrel, Inc., now managed by Microchip Technology. The series focuses on ECL and PECL compatible components designed for demanding high-frequency applications requiring precise timing and signal integrity.

Translators, Level Shifters Replacement Considerations

Consult official documentation for direct substitutes. Cross-reference pinouts and electrical characteristics carefully if considering alternative translators.
