SY100EPT28LZG-TR

Translators, Level Shifters Overview

The SY100EPT28LZG-TR is a differential LVPECL-to-LVTTL translator and an LVTTL-to-differential LVPECL translator manufactured by Microchip Technology. It operates on a single +3.3V power supply within the 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 reliably in industrial temperature ranges from –40°C to +85°C.

Translators, Level Shifters Feature Summary

• Dual-direction translation between differential LVPECL and LVTTL logic levels within a single package
• Requires only a +3.3V power supply and ground, eliminating the need for negative voltage rails
• Temperature-compensated design ensures constant logic levels across the operating temperature range
• Internal biasing on open inputs forces stability to prevent undefined states

Translators, Level Shifters Applications

• Backplane signal transmission and reception
• System interconnects requiring mixed logic level translation
• High-speed digital communication interfaces

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'ZG-TR' corresponds to the 8-Lead SOIC package with tape and reel packaging containing 1,000 units per reel. Confirm that the component meets Pb-Free NiPdAu specifications. Ensure the procurement channel provides valid traceability codes matching the manufacturer's marking requirements.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between LVPECL and LVTTL is required without multiple discrete devices. It is suitable for designs constrained by space due to its small outline 8-pin package. Verify that the system operates strictly within the +3.0V to +3.6V supply voltage range and requires operation within the specified industrial temperature limits.

Translators, Level Shifters Part Context

This part belongs to the SY100 series of high-speed logic translators produced by Microchip Technology. The series includes variants available in different packages such as MSOP and SOIC. The ZG suffix indicates the SOIC package variant, while the TR suffix denotes the tape and reel packaging format intended for automated assembly processes.

Translators, Level Shifters FAQ

How does the device handle open input conditions?

Under open input conditions, the /D_LVPECL input is biased at VCC/2 and the D_LVPECL input is pulled to GND. This configuration forces the Q_LVTTL output to a low state, ensuring circuit stability.

What are the termination recommendations for LVPECL outputs?

The datasheet recommends parallel termination using a Thevenin equivalent or a three-resistor Y termination. For a 3.3V supply, the resistor Rb should be between 46Ω and 50Ω to set the DC voltage equal to Vt.
