SY89323LMI-TR

Translators, Level Shifters Overview

The SY89323LMI-TR is a dual differential LVPECL-to-LVTTL translator manufactured by Microchip Technology. It operates on a single +3.3V power supply and features an ultra-small 8-pin MLF® (2mm × 2mm) package with an exposed pad. The device provides two independent translation channels, converting differential Low Voltage Positive ECL inputs to single-ended LVTTL outputs. Key electrical specifications include a maximum input frequency of 275MHz, a typical propagation delay of 1.9ns, and a maximum part-to-part skew of 0.5ns. Internal pull-up and pull-down resistors are integrated for input management.

Translators, Level Shifters Feature Summary

• Dual channel architecture translates differential LVPECL signals to single-ended LVTTL levels within a compact footprint.
• Integrated internal input resistors ensure defined logic states when inputs are left open or floating.
• Flow-through pinout design facilitates efficient printed circuit board layout and signal routing.

Translators, Level Shifters Applications

• Clock and data signal translation in space-constrained designs
• Interfacing LVPECL sources with LVTTL destination logic
• High-speed digital communication systems requiring minimal skew

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and lead finish. The 'G' suffix typically indicates a Pb-Free variant with NiPdAu finish, while other suffixes may denote Sn-Pb finishes. Confirm that the component meets RoHS requirements if applicable to your manufacturing process. Ensure the exposed pad is properly soldered to the ground plane for thermal management as specified in the datasheet.

Translators, Level Shifters Selection Notes

Select this component when a dual-channel level shifter is required between LVPECL and LVTTL domains. The choice is driven by the need for a small 8-pin MLF package and low skew performance. Consider the 3.3V operating voltage and the internal resistor configurations for input handling. This device serves as a functional equivalent to older generations like the SY100EPT23L but offers a significantly reduced physical footprint.

Translators, Level Shifters Part Context

This part belongs to the Precision Edge series of high-performance mixed-signal ICs originally developed by Micrel, Inc., which was later acquired by Microchip Technology. The SY89323L specifically addresses the market demand for compact clock translators. It replaces larger packages previously used for similar functionality, enabling denser circuit board designs in modern electronics.

Translators, Level Shifters Replacement Considerations

The SY100EPT23L is functionally equivalent but utilizes a different package type. Verify pin compatibility and package dimensions before substitution. Other parts in the SY8932x family may offer single-channel variants or different package options depending on channel count requirements.
