SY100ELT21LZI-TR

Translators, Level Shifters Overview

The SY100ELT21LZI-TR is a single differential LVPECL-to-LVTTL translator from the Precision Edge family, designed for industrial temperature ranges (-40°C to +85°C). It operates on a single +3.3V supply and features a typical propagation delay of 2.0ns with a maximum input frequency of 275MHz. The device utilizes an 8-pin SOIC package and provides 24mA TTL outputs. It supports differential, single-ended, or AC-coupled interfaces via the VBB reference output.

Translators, Level Shifters Feature Summary

• Translates differential LVPECL signals to LVTTL levels using a single 3.3V power supply
• Provides low skew performance suitable for high-speed clock and data signal translation
• Includes internal biasing that forces the output low under open input conditions for added stability

Translators, Level Shifters Applications

• Clock signal translation in space-constrained designs
• Data signal level shifting between LVPECL sources and LVTTL destinations
• Industrial applications requiring low power consumption and minimal footprint

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'ZITR' confirms the Industrial operating temperature range (-40°C to +85°C), the Z8-1 8-pin SOIC package type, and the Tape and Reel packaging format. Ensure compatibility with the required logic standards (100ELT compatible with positive ECL 100K levels) before procurement.

Translators, Level Shifters Selection Notes

Select this component when translating LVPECL inputs to LVTTL outputs is required within a single 3.3V system. It is appropriate for designs prioritizing low power, small physical size, and stable operation under varying industrial temperature conditions compared to commercial grade alternatives.

Translators, Level Shifters Part Context

This part belongs to the Precision Edge SY10/100ELT21L series manufactured by Micrel, now Microchip Technology. The '100' designation indicates compatibility with positive ECL 100K logic levels, distinguishing it from the '10' variant which supports 10H levels. The 'I' suffix denotes the industrial temperature rating.

Translators, Level Shifters Replacement Considerations

SY100ELT21LZCTR serves as a direct replacement if commercial temperature range suffices. For lead-free industrial requirements, verify availability of SY100ELT21LZGTR.
