SY10ELT21LZG

Translators, Level Shifters Overview

The SY10ELT21LZG 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 a temperature range from -40°C to +85°C and includes a VBB reference output.

Translators, Level Shifters Feature Summary

• Translates differential LVPECL signals to LVTTL levels using a single 3.3V supply
• Features low skew single gate design suitable for clock or data signal translation
• Includes internal biasing that forces the output low under open input conditions

Translators, Level Shifters Applications

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 a VCC/2 voltage level while the D input is pulled to ground, forcing the Q output low to provide added stability.

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.
