SY100ELT28ZG-TR

Translators, Level Shifters Overview

The SY100ELT28ZG-TR is a dual translation logic IC manufactured by Microchip Technology, integrating a differential PECL-to-TTL translator and a TTL-to-differential PECL translator within a single package. Designed for +5V power supply operation, it facilitates signal conversion across backplanes. The device supports a maximum toggle frequency of 160 MHz for TTL interfaces and guarantees propagation delays under 5.5 ns for PECL-to-TTL conversion and under 1.3 ns for TTL-to-PECL conversion. It operates reliably within an industrial temperature range of –40 °C to +85 °C.

Translators, Level Shifters Feature Summary

• Integrates bidirectional translation between differential PECL and standard TTL logic levels in a compact design.
• Features internal PECL input pulldown resistors and defined default output states when inputs are left open.
• Supports high-speed signal transmission with guaranteed AC parameters over the full operating temperature range.

Translators, Level Shifters Applications

• Backplane signal transmission systems
• Differential PECL to TTL level translation
• TTL to differential PECL level translation

Translators, Level Shifters Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence or lifecycle changes. Confirm that the specific ordering suffix matches the required package type and temperature grade. Ensure compatibility with existing +5V power supply architectures before procurement.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between PECL and TTL domains is required within a single footprint. Verify that the system operates on a +5V supply rail. Consider the 8-pin MSOP or SOIC package availability based on board space constraints and thermal requirements.

Translators, Level Shifters Part Context

This component belongs to the SY10/100ELT series of voltage level translators produced by Micrel, now part of Microchip Technology. The '100' designation typically indicates higher speed or performance characteristics compared to the '10' series variants within the same functional family.

Translators, Level Shifters FAQ

What are the default output states if the inputs are left open?

If inputs are left open or below 1.3V, the QTTL output defaults low, while the QECL output defaults high.

Does the device require a negative voltage supply?

No, because PECL levels are used, only a +5V positive supply and ground are required.
