SY10ELT21LZI

Translators, Level Shifters Overview

The SY10ELT21LZI is a single differential LVPECL-to-LVTTL translator manufactured by Microchip Technology. It operates on a single +3.3V power supply and features a typical propagation delay of 2.0ns with a maximum input frequency of 275MHz. The device provides 24mA TTL outputs and utilizes an 8-pin SOIC package. Designed for industrial applications, it supports operating temperatures from -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Translates differential LVPECL signals to LVTTL levels using a single 3.3V supply
• Provides high-speed translation with low skew and minimal space requirements
• Includes internal biasing to force the output low under open input conditions

Translators, Level Shifters Applications

• Clock signal translation in embedded systems
• Data signal level shifting between PECL and TTL domains
• High-speed interface circuits requiring low power consumption

Translators, Level Shifters Procurement Notes

Verify that the component matches the specific industrial temperature range (-40°C to +85°C) required for your application environment. Confirm the package type is the 8-lead Small Outline Integrated Circuit (SOIC). Ensure the ordering suffix corresponds to the correct lead finish and tape-and-reel packaging if applicable.

Translators, Level Shifters Selection Notes

Select this component when translating LVPECL sources to LVTTL loads within a 3.3V system. It is suitable for designs prioritizing low power and compact footprint over higher voltage compatibility. Verify that the load capacitance does not exceed 20pF to maintain specified timing parameters.

Translators, Level Shifters Part Context

This part belongs to the Precision Edge ELT21L family of translators. It is functionally similar to the SY100ELT21L but optimized for Positive ECL 10H logic levels rather than 100K levels. Both variants share the same pinout and electrical characteristics except for specific input voltage thresholds.

Translators, Level Shifters FAQ

How does the device behave if the inputs are left open?

Under open input conditions, the /D input is biased at VCC/2 and the D input is pulled to ground, forcing the Q output low to provide added stability.

What is the purpose of the VBB pin?

The VBB pin serves as a reference output that allows for differential, single-ended, or AC-coupled interfaces to the device.
