SY100EL91LZC-TR

Translators, Level Shifters Overview

The SY100EL91LZC-TR is a triple LVPECL-to-ECL or LVPECL-to-LVECL translator manufactured by Microchip Technology. It operates with a +3.3V VCC supply and supports negative VEE rails of -5.0V for ECL or -3.3V for LVECL configurations. The device features a fully differential design with a typical propagation delay of 620ps. It is housed in a 20-pin wide SOIC package (Z20-1) and includes a PECL_VBB output pin to facilitate interfacing with single-ended PECL signals.

Translators, Level Shifters Feature Summary

• Provides three independent channels for translating LVPECL input signals to either standard ECL or Low Voltage ECL outputs.
• Includes a dedicated PECL_VBB reference voltage output designed to support single-ended input switching conditions.
• Utilizes a fully differential architecture to ensure signal integrity across the translation process.

Translators, Level Shifters Applications

• Interfacing LVPECL sources with ECL-based logic circuits
• Level translation between LVPECL and LVECL domains
• System designs requiring conversion from single-ended PECL inputs to differential ECL outputs

Translators, Level Shifters Procurement Notes

Verify that the specific ordering suffix matches the required lead finish and temperature range, as the datasheet distinguishes between commercial and industrial grades. Confirm whether the tape and reel packaging variant is necessary for automated assembly processes. Ensure compatibility with the specified power supply voltages before procurement.

Translators, Level Shifters Selection Notes

Select this component when a system requires converting three separate LVPECL signals to ECL or LVECL levels within a single integrated circuit. Consider the operating temperature range requirements, as industrial variants are available alongside commercial options. Evaluate the need for single-ended input support, which utilizes the internal VBB reference generation capability.

Translators, Level Shifters Part Context

This part belongs to the SY100EL91L series of translators produced by Micrel, now part of Microchip Technology. The series focuses on high-speed level shifting between low voltage positive emitter coupled logic and emitter coupled logic standards. The ZC suffix indicates a commercial grade device with Sn-Pb lead finish in a 20-pin wide SOIC package.

Translators, Level Shifters Replacement Considerations

SY100EL91LZG is a lead-free industrial grade alternative in the same package. SY100EL91LZI offers an industrial temperature range with Sn-Pb finish. Verify pinout compatibility and electrical specifications against current design requirements before substitution.
