SY10EPT28LKG

Translators, Level Shifters Overview

The SY10EPT28LKG is a differential LVPECL-to-LVTTL translator and LVTTL-to-differential LVPECL translator manufactured by Microchip Technology. It operates on a single +3.3V ±10% power supply, eliminating the need for negative voltage rails. The device supports maximum frequencies exceeding 275MHz for LVTTL and 700MHz for LVPECL toggle modes. Propagation delays are less than 600ps for LVTTL-to-LVPECL conversion and under 2ns for LVPECL-to-LVTTL translation. It features internal 75kΩ input pull-down resistors and functions within an industrial temperature range of –40°C to +85°C.

Translators, Level Shifters Feature Summary

• Dual-directional translation between Low Voltage TTL (LVTTL) and Low Voltage Positive ECL (LVPECL) logic levels in a single package
• Requires only a positive 3.3V power supply and ground, simplifying power distribution compared to traditional ECL systems
• Includes internal 75kΩ input pull-down resistors to maintain signal stability when inputs are left open
• Designed with small outline packaging to facilitate signal transmission across backplanes

Translators, Level Shifters Applications

• Backplane signal transmission applications requiring mixed logic level interfacing
• Systems utilizing LVPECL sources connected to LVTTL destinations
• Circuits converting LVTTL signals to differential LVPECL outputs

Translators, Level Shifters Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the datasheet lists distinct part numbers for MSOP and SOIC variants. Confirm lead time requirements with the manufacturer or distributor, noting that production cycles may vary based on current demand. Ensure compliance with RoHS directives if Pb-Free versions are specified for new designs.

Translators, Level Shifters Selection Notes

Select this component when a design requires bidirectional translation between LVTTL and LVPECL domains without complex external biasing networks. The integrated pull-down resistors reduce external component count. Verify that the system operates within the specified 3.3V supply tolerance and that the propagation delay characteristics meet the timing constraints of the target interface.

Translators, Level Shifters Part Context

This device belongs to the ECL Pro™ family, which provides high-speed logic solutions compatible with industry standards. The product line includes variations such as the SY100EPT28L, which offers temperature compensation for constant logic levels over the operating range. The series is designed for performance-critical applications where signal integrity and speed are paramount.

Translators, Level Shifters Replacement Considerations

The SY100EPT28L is a documented alternative within the same family that provides temperature-compensated logic levels. Verify pinout compatibility and ensure that the AC electrical parameters of the substitute meet the specific frequency and delay requirements of the application.
