SY89328LMG-TR

Translators, Level Shifters Overview

The SY89328LMG-TR is a mixed-signal translator manufactured by Microchip Technology, housed in an 8-MLF (2mm × 2mm) surface-mount package. It provides bidirectional translation between differential LVPECL and single-ended LVTTL signals within a single device. The component operates on a +3.3V ±10% power supply with an industrial temperature range of –40°C to +85°C. Maximum operating frequencies are specified at 700MHz for LVPECL and 275MHz for LVTTL. Propagation delays are less than 2ns for LVPECL-to-LVTTL conversion and under 600ps for LVTTL-to-LVPECL conversion.

Translators, Level Shifters Feature Summary

• Provides dual-directional signal translation between differential LVPECL and single-ended LVTTL logic levels.
• Features internal 75kΩ pull-up and pull-down resistors on the LVPECL input stage.
• Utilizes an ultra-small 8-pin MLF™ package with a significantly reduced footprint compared to traditional leaded packages.
• Requires only a positive power supply and ground connection due to LVPECL level compatibility.

Translators, Level Shifters Applications

• Backplane signal transmission and reception
• LVPECL to LVTTL interface bridging
• LVTTL to differential LVPECL translation

Translators, Level Shifters Procurement Notes

Verify that the specific ordering suffix matches the required lead finish, as the 'G' suffix indicates a Pb-Free bar-line indicator with NiPdAu plating. Confirm the package type corresponds to the 8-lead MLF™ configuration. Ensure the design accounts for the exposed pad requirement, which must be soldered to a ground plane for proper thermal management and electrical grounding.

Translators, Level Shifters Selection Notes

Select this component when space constraints require an ultra-small outline package for high-speed logic translation. It is suitable for designs requiring simultaneous conversion from LVPECL to LVTTL and vice versa without using separate unidirectional devices. Verify that the system operates within the specified 3.0V to 3.6V supply voltage range and that the frequency requirements do not exceed the guaranteed AC parameters for the respective logic families.

Translators, Level Shifters Part Context

This part belongs to the Precision Edge® series of high-speed logic products originally developed by Micrel, Inc., which was subsequently acquired by Microchip Technology. The SY89328L serves as a functional equivalent to the SY100EPT28L but offers a much smaller physical footprint. The product line focuses on low-power, high-performance translation solutions for digital communication interfaces.

Translators, Level Shifters Replacement Considerations

The datasheet identifies the SY100EPT28L as a functionally equivalent alternative. However, the SY100EPT28L utilizes a different package style and does not share the same ultra-small MLF™ form factor. Designers must evaluate board space and pinout compatibility before substituting.
