Key Parameters

Substitute Part Grouping Explanation

Substitution of the SY89306VMI TR is determined by strict equivalence across the following critical parameters:

• Single channel Buffer/ReDriver configuration
• ECL input and ECL output signal compatibility
• 300ps propagation delay time
• 8-MLF® (2x2) package footprint and pinout
• Surface mount mounting type
• 3V to 5.5V supply voltage range
• 48mA supply current specification
• -40°C to 85°C operating temperature range
• Precision Edge® series classification

The SY89306VMG-TR meets all these electrical and mechanical requirements, providing direct functional equivalence while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SY89306VMG-TR is the direct parametric equivalent for the obsolete SY89306VMI TR. Both components share identical electrical specifications and mechanical packaging, ensuring pin-for-pin compatibility and functional interchangeability in circuit applications.

The SY89306VMG-TR offers two significant advantages over the main part: Active product status ensures long-term availability and manufacturing support, and ROHS3 compliance satisfies modern environmental and regulatory requirements, whereas the SY89306VMI TR carries RoHS non-compliant status. For new designs and ongoing production requiring ECL/PECL buffer/redrive functionality in the 8-MLF® package, the SY89306VMG-TR is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the SY89306VMG-TR be used as a direct replacement for the SY89306VMI TR?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including signal type, delay time, supply voltage, current consumption, temperature range, and package configuration. The SY89306VMG-TR provides direct pin-for-pin substitution.

Q: What is the difference between the SY89306VMI TR and SY89306VMG-TR?

A: The primary differences are product status and compliance. The SY89306VMI TR is obsolete with RoHS non-compliant status, while the SY89306VMG-TR is active and ROHS3 compliant. All electrical and mechanical specifications remain identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both components use the 8-VFDFN Exposed Pad, 8-MLF® (2x2) package with identical pinout and footprint. Surface mount assembly processes require no modification.

Q: What supply voltage range do these parts support?

A: Both the SY89306VMI TR and SY89306VMG-TR operate across a 3V to 5.5V supply voltage range with 48mA supply current.

Q: What is the propagation delay specification for these buffer/redrive ICs?

A: Both parts specify 300ps delay time for ECL signal conditioning applications.

Q: Why is the SY89306VMI TR listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The SY89306VMG-TR provides continued access to this functionality with active manufacturing support.
