SY89323LMG-TR

Translators, Level Shifters Overview

The SY89323LMG-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 275 MHz, a typical propagation delay of 1.9 ns, and a maximum propagation delay of 2.5 ns. The outputs are capable of sourcing up to 24 mA.

Translators, Level Shifters Feature Summary

• Dual-channel architecture for simultaneous conversion of differential LVPECL signals to single-ended LVTTL levels
• Ultra-small 8-pin MLF® package design providing a significantly reduced footprint compared to traditional packages
• Integrated internal pull-up and pull-down resistors on inputs to ensure defined logic states when signals are open or floating
• Compatible with standard differential LVPECL inputs referenced to a 3.3V supply

Translators, Level Shifters Applications

• Translation of clock signals in space-constrained digital systems
• Conversion of data signals between LVPECL and LVTTL domains
• High-speed interface bridging in telecommunications equipment

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'MG' corresponds to the Pb-Free NiPdAu lead finish as documented in the manufacturer's ordering information. Confirm that the component is sourced from authorized distribution channels to ensure authenticity. Check for moisture sensitivity level requirements and appropriate dry-packaging handling procedures prior to assembly. Ensure the supplier documentation matches the exact part number SY89323LMG-TR.

Translators, Level Shifters Selection Notes

Select this component when a compact solution is required for translating differential LVPECL signals to LVTTL logic levels. The device is suitable for designs constrained by board space due to its 2mm x 2mm MLF® package. It is appropriate for applications requiring a single 3.3V power supply and high-frequency signal integrity up to 275 MHz. Consider the internal input termination features if external biasing components need to be minimized.

Translators, Level Shifters Part Context

The SY89323L belongs to Micrel's Precision Edge® family of high-speed logic devices, now managed under Microchip Technology following acquisition. This series focuses on low-power, high-performance translators and buffers designed for modern digital interfaces. The SY89323L specifically addresses the need for small form-factor solutions in clock and data distribution networks where space is at a premium.

Translators, Level Shifters Replacement Considerations

The datasheet notes functional equivalence to the SY100EPT23L, though pinouts and packaging differ significantly. Verify compatibility if substituting based on function alone.
