SY100EPT28LKI-TR

Translators, Level Shifters Overview

The SY100EPT28LKI-TR is a dual translation translator from the ECL Pro series, manufactured by Microchip Technology. It integrates LVPECL-to-LVTTL and LVTTL-to-differential LVPECL conversion in an 8-pin MSOP package. The device operates on a single +3.3V ±10% power supply. It supports maximum frequencies of 700 MHz for LVPECL outputs and 275 MHz for LVTTL outputs. Propagation delays are less than 2 ns for LVPECL-to-LVTTL conversion and less than 600 ps for LVTTL-to-LVPECL conversion. It includes internal 75kΩ input pull-down resistors and functions within an industrial temperature range of –40 °C to +85°C.

Translators, Level Shifters Feature Summary

• Provides bidirectional translation between Low Voltage TTL (LVTTL) and differential Low Voltage Positive ECL (LVPECL) signals.
• Operates exclusively with a single +3.3V power supply, eliminating the need for negative voltage rails.
• Features integrated 75kΩ internal pull-down resistors on the differential LVPECL inputs.

Translators, Level Shifters Applications

• Backplane signal transmission and reception
• System board interconnects requiring mixed logic level translation

Translators, Level Shifters Procurement Notes

Verify that the component is sourced from authorized channels due to its status as a legacy product originally manufactured by Micrel. Confirm the specific ordering suffix matches the required tape and reel packaging and lead finish specifications. Ensure the procurement documentation aligns with the current manufacturer's part numbering conventions following corporate acquisitions.

Translators, Level Shifters Selection Notes

Select this component when designing systems that require interfacing between LVTTL and LVPECL domains using a single 3.3V supply. It is suitable for applications needing compact 8-pin surface-mount solutions. Verify that the required propagation delay and frequency specifications fall within the guaranteed AC parameters provided in the datasheet for the industrial temperature range.

Translators, Level Shifters Part Context

This component belongs to the ECL Pro family, which provides high-speed logic solutions optimized for low-voltage operation. Originally developed by Micrel, Inc., the product line was integrated into Microchip Technology's portfolio. The 100k series designation indicates the inclusion of temperature compensation to maintain constant logic levels across the operating temperature range.

Translators, Level Shifters Replacement Considerations

Check for the SY10EPT28L variant, which shares identical electrical characteristics but may differ in manufacturing lot markings or specific supplier distribution channels. Verify package compatibility if substituting between MSOP and SOIC footprints.
