SY89833LMI-TR Clock Fanout Buffer Equivalent & Substitute Parts

Part Overview

The SY89833LMI-TR is a Clock Fanout Buffer (Distribution) Translator IC manufactured by Microchip Technology, designed for 1:4 clock distribution at frequencies up to 2 GHz. This part operates with differential inputs and outputs, supporting CML, LVDS, and LVPECL input standards with LVDS output. The SY89833LMI-TR is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing system designs and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SY89833LMI-TR is determined by the following critical parameters:

• Functional Equivalence: 1:4 fanout buffer ratio with differential input and output capability
• Frequency Rating: Maximum 2 GHz operation
• Signal Standards: Support for CML, LVDS, and LVPECL inputs with LVDS output
• Electrical Specifications: 3V to 3.6V supply voltage range and -40°C to 85°C operating temperature
• Package Compatibility: 16-pin VFQFN with exposed pad in 3x3mm footprint
• Mounting: Surface mount technology

Substitute parts are grouped into two categories:

Parametric Equivalents (Microchip Technology): SY89833ALMG-TR and SY89833LMG-TR maintain identical electrical and functional specifications with variations in packaging format and RoHS compliance status.

Direct Manufacturer Equivalent (onsemi): NB6N14SMNR2G provides functional equivalence from an alternative manufacturer with identical electrical performance and package footprint.

Parameter Comparison

Engineering Selection Recommendations

SY89833ALMG-TR is the primary parametric equivalent from Microchip Technology. This part maintains full electrical and functional compatibility with the SY89833LMI-TR while offering active product status and ROHS3 compliance. The higher MSL rating (3, 168 Hours) requires standard moisture control during storage and assembly.

SY89833LMG-TR provides an alternative Microchip option with improved moisture sensitivity characteristics (MSL 2, 1 Year) and the highest current inventory availability (2400 Pcs). The Cut Tape and Digi-Reel® packaging format accommodates different procurement workflows.

NB6N14SMNR2G from onsemi delivers functional equivalence with identical electrical specifications and package footprint. This part offers MSL 1 (Unlimited) moisture sensitivity and active product status. Selection of this alternative introduces a secondary manufacturer into the supply chain while maintaining full parametric compatibility.

All three substitute parts are ROHS3 compliant and REACH unaffected, supporting modern regulatory requirements. The choice between Microchip and onsemi options depends on supply chain strategy, inventory requirements, and manufacturer qualification procedures.

Frequently Asked Questions (FAQ)

Q: Can SY89833ALMG-TR directly replace SY89833LMI-TR in existing designs?

A: Yes. Both parts share identical electrical specifications, frequency ratings, input/output standards, supply voltage range, operating temperature range, and package footprint (16-VFQFN 3x3mm). Pin-for-pin compatibility is maintained.

Q: What is the difference between SY89833ALMG-TR and SY89833LMG-TR?

A: Both are Microchip parametric equivalents with identical electrical performance. The primary differences are packaging format (Tape & Reel vs. Cut Tape/Digi-Reel®) and moisture sensitivity level (MSL 3 vs. MSL 2). Selection depends on procurement format preference and storage environment conditions.

Q: Is NB6N14SMNR2G compatible with designs using SY89833LMI-TR?

A: Yes. The onsemi NB6N14SMNR2G maintains identical electrical specifications, frequency rating, signal standards, supply voltage, operating temperature, and package footprint. The part is functionally equivalent and pin-compatible.

Q: What does MSL (Moisture Sensitivity Level) mean for component selection?

A: MSL indicates the maximum time a component can be exposed to moisture before assembly. SY89833LMI-TR and NB6N14SMNR2G have MSL 1 (Unlimited exposure). SY89833LMG-TR has MSL 2 (1 Year storage limit). SY89833ALMG-TR has MSL 3 (168 Hours storage limit). Higher MSL ratings require more stringent moisture control during storage and handling.

Q: Are all substitute parts ROHS3 compliant?

A: SY89833ALMG-TR, SY89833LMG-TR, and NB6N14SMNR2G are all ROHS3 compliant. The original SY89833LMI-TR is RoHS non-compliant. Substitution with any of these parts upgrades compliance status for new designs.

Q: What is the package difference between 16-MLF® and 16-QFN?

A: Both designations refer to 16-pin Very Fine Pitch Quad Flat No-Lead packages in 3x3mm footprint. The terminology difference reflects manufacturer naming conventions (Microchip uses MLF®, onsemi uses QFN). The physical package and pin layout are equivalent.

Q: Which substitute part has the best inventory availability?

A: SY89833LMG-TR offers the highest current inventory at 2400 Pcs, followed by SY89833ALMG-TR at 1734 Pcs and NB6N14SMNR2G at 1373 Pcs.
