SY10ELT21LZC

Translators, Level Shifters Overview

The SY10ELT21LZC 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. It supports commercial temperature ranges from -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Translates differential LVPECL signals to LVTTL levels using a single 3.3V supply
• Features low skew design suitable for clock or data signal translation
• Includes VBB reference output for flexible interface configurations

Translators, Level Shifters Applications

• Clock signal translation in high-speed digital systems
• Data signal level shifting between PECL and TTL domains
• Low-power embedded designs requiring minimal space

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix ZC confirms the commercial operating temperature range (-40°C to +85°C) and Sn-Pb lead finish as documented in the official datasheet. Confirm that the Z8-1 package designation matches the required 8-pin SOIC footprint for your PCB layout. Ensure compatibility with existing system voltage requirements before procurement.

Translators, Level Shifters Selection Notes

Select this component when translating LVPECL sources to TTL loads within a 3.3V environment. The SY10ELT21L variant specifically targets Positive ECL 10H logic levels, distinguishing it from the 100ELT series which supports 100K levels. Consider the 2.0ns typical delay and 275MHz maximum frequency for timing-critical applications.

Translators, Level Shifters Part Context

This part belongs to the Precision Edge SY10/100ELT21L family of translators designed for low power and small form factor implementations. Manufactured originally by Micrel, Inc., the product line is now managed by Microchip Technology. The family includes variants optimized for different ECL standards and temperature grades.

Translators, Level Shifters Replacement Considerations

SY100ELT21LZC: Compatible alternative supporting Positive ECL 100K logic levels instead of 10H.

Translators, Level Shifters FAQ

What is the function 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.

How does the device behave under open input conditions?

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