Key Parameters

Substitute Part Grouping Explanation

Substitution of the SY89876LMI TR is determined by the following critical parameters:

• Ratio - Input:Output: Must be 1:2 for functional equivalence
• Frequency - Max: Must support 2 GHz operation
• Voltage - Supply: Must operate within 2.97V ~ 3.63V range
• Operating Temperature: Must support -40°C ~ 85°C range
• Package / Case: Must be 16-VFQFN Exposed Pad, 16-MLF® for mechanical compatibility
• Differential Input/Output: Must support Yes/Yes configuration
• Input Standards: Must support CML, HSTL, LVDS, LVPECL
• Output Standard: Must be LVDS

The SY89876LMG-TR meets all these criteria as a parametric equivalent, differing only in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The SY89876LMG-TR is the direct parametric equivalent for the obsolete SY89876LMI TR. Both parts share identical electrical and mechanical specifications, ensuring functional compatibility in existing designs. The primary distinctions are product status and compliance certifications.

The SY89876LMG-TR offers advantages for new designs and ongoing production:

• Active product status ensures continued availability and manufacturer support
• ROHS3 compliance meets current environmental regulations
• Moisture Sensitivity Level 2 (1 Year) is standard for modern surface-mount components

For legacy systems currently using the SY89876LMI TR, the SY89876LMG-TR provides a direct replacement without circuit redesign or layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the SY89876LMG-TR directly replace the SY89876LMI TR in existing designs?
