SY100EL91LZI-TR

Translators, Level Shifters Overview

The SY100EL91LZI-TR is a triple LVPECL-to-ECL or LVPECL-to-LVECL translator manufactured by Microchip Technology. It operates with a VCC supply of 3.0V to 3.8V and requires three power rails for level translation. The device features a propagation delay of 620ps typical, output rise/fall times of 400ps typical, and supports low voltage operation. It is housed in a 20-pin Wide SOIC package (Z20-1) and is rated for an industrial operating temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Provides full differential design for signal integrity
• Supports single-ended PECL input interfacing via dedicated reference voltage output
• Capable of translating between LVPECL and ECL/LVECL logic levels

Translators, Level Shifters Applications

• Level translation between LVPECL sources and ECL receivers
• Level translation between LVPECL sources and LVECL receivers
• Interfacing single-ended PECL signals to differential ECL inputs

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'TR' indicates tape and reel packaging as documented in the official datasheet. Confirm that the 'ZI' suffix corresponds to the industrial temperature range (-40°C to +85°C). Ensure compatibility with the required 20-pin Wide SOIC footprint during procurement planning.

Translators, Level Shifters Selection Notes

Select this component when interfacing LVPECL drivers with ECL or LVECL loads requiring high-speed translation. Consider the requirement for three distinct power rails (VCC, VEE, GND) and the need for external bypass capacitors. Evaluate the 620ps propagation delay against system timing constraints.

Translators, Level Shifters Part Context

This part belongs to the SY100EL91L series of translators. It is functionally related to other variants such as SY100EL91LZC (commercial grade) and SY100EL91LZG (lead-free industrial). The manufacturer transitioned from Micrel to Microchip Technology, maintaining the same functional specifications across these identifiers.

Translators, Level Shifters Replacement Considerations

SY100EL91LZITR is a direct equivalent offering identical functionality in tape and reel packaging. SY100EL91LZGTR provides the same industrial performance but utilizes lead-free NiPdAu finishes.
