SY100EPT28LZG

Translators, Level Shifters Overview

The SY100EPT28L is a differential LVPECL-to-LVTTL translator and an LVTTL-to-differential LVPECL translator in a single package. It operates on a +3.3V power supply with a range of +3.0V to +3.6V. The device supports maximum frequencies of 700 MHz for LVPECL outputs and 275 MHz for LVTTL outputs. Propagation delay is less than 2.5 ns for LVPECL-to-LVTTL conversion and less than 600 ps for LVTTL-to-LVPECL conversion. It functions within an industrial temperature range of –40°C to +85°C and is available in 8-lead MSOP and SOIC packages.

Translators, Level Shifters Feature Summary

• Dual translation design combining LVPECL-to-LVTTL and LVTTL-to-LVPECL converters in one package
• Temperature compensation ensures constant logic levels across the operating temperature range
• Internal biasing forces Q_LVTTL low under open input conditions to ensure stability

Translators, Level Shifters Applications

• Sending and receiving signals across backplanes
• Interfacing between LVPECL and LVTTL logic domains
• High-speed data transmission systems requiring voltage level translation

Translators, Level Shifters Procurement Notes

Verify the specific package variant (SOIC or MSOP) and ordering suffix required for your application, as these determine the physical form factor and reel/tube packaging configuration. Confirm that the +3.3V supply voltage falls within the specified operational range of +3.0V to +3.6V. Ensure thermal management considerations align with the package thermal resistance ratings provided in the datasheet for your expected airflow conditions.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between LVPECL and LVTTL signals is required within a compact footprint. The device is suitable for designs needing guaranteed AC parameters over temperature, specifically propagation delays under 2.5 ns and 600 ps respectively. Consider the 8-lead MSOP or SOIC package options based on board space constraints and assembly preferences.

Translators, Level Shifters Part Context

The SY100EPT28L belongs to Microchip's EPT series of translators, designed for high-speed signal integrity applications. It replaces older versions like the SY10EPT28L and is part of the 100k series which includes temperature compensation features. This family focuses on providing reliable voltage level shifting between different logic standards without requiring complex external termination networks beyond standard recommendations.
