SY10EPT28LKG-TR

Translators, Level Shifters Overview

The SY10EPT28LKG-TR is a mixed-signal translator from the ECL Pro series, manufactured by Microchip Technology. It integrates dual translation functions: LVPECL-to-LVTTL and LVTTL-to-differential LVPECL. The device operates on a single +3.3V ±10% power supply. Key electrical parameters include a maximum frequency 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 features internal 75kΩ input pull-down resistors and is housed in an 8-pin MSOP package.

Translators, Level Shifters Feature Summary

• Dual-directional signal translation between Low Voltage TTL (LVTTL) and differential Low Voltage Positive ECL (LVPECL) levels within a single integrated circuit.
• Operates exclusively with a +3.3V power supply, eliminating the need for negative voltage rails typically required by standard ECL logic families.
• Incorporates internal 75kΩ pull-down resistors on the differential LVPECL inputs to simplify biasing requirements.
• Designed for high-speed backplane applications with guaranteed AC performance across the industrial temperature range.

Translators, Level Shifters Applications

• Backplane signal transmission and reception where mixed logic families interface.
• System designs requiring translation between LVTTL control signals and LVPECL high-speed data paths.
• High-frequency digital circuits operating up to 700 MHz toggle frequency.

Translators, Level Shifters Procurement Notes

Verify that the component matches the specific K8-1 package marking HP28 and the Pb-Free designation indicated by the KG suffix. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering suffix corresponds to the Tape and Reel packaging format. Cross-reference the part number against the official Micrel/Microchip database to validate current production status and availability.

Translators, Level Shifters Selection Notes

Select this component when a design requires bidirectional level shifting between LVTTL and LVPECL domains without external discrete components. It is suitable for systems constrained to a single 3.3V supply rail. Consider the 8-pin MSOP footprint for space-sensitive layouts. Verify that the load capacitance and termination requirements align with the specified AC characteristics for the target frequency.

Translators, Level Shifters Part Context

This device belongs to the ECL Pro family, originally developed by Micrel, Inc., which was acquired by Microchip Technology. The product line focuses on high-speed ECL-compatible logic optimized for 3.3V operation. The SY10/100EPT28L specifically addresses the need for compact, dual-function translators in high-density electronic assemblies.
