SY89313VMI-TR Equivalent & Substitute Parts

Part Overview

The SY89313VMI-TR is a Clock Generator IC manufactured by Microchip Technology, designed for high-speed timing applications up to 4GHz. This component operates with ECL/PECL input and output signaling, supporting a 1:1 input-to-output ratio in a compact 8-VFDFN surface mount package. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SY89313VMI-TR is determined by strict equivalence across the following critical parameters:

Electrical compatibility requires matching input/output signal types (ECL/PECL), maximum frequency rating (4GHz), supply voltage range (3V ~ 5.5V), and operating temperature range (-40°C ~ 85°C). Mechanical compatibility requires identical package type (8-VFDFN Exposed Pad, 8-MLF®) and surface mount mounting configuration. Functional compatibility requires matching circuit count (1) and input-to-output ratio (1:1).

The SY89312VMG-TR meets all these criteria as a parametric equivalent from the same manufacturer series (Precision Edge®), with identical electrical specifications and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The SY89312VMG-TR is the direct parametric equivalent for the discontinued SY89313VMI-TR. Both components share identical electrical and mechanical specifications, enabling direct substitution in existing designs without circuit modification.

The SY89312VMG-TR offers additional advantages: it maintains active product status with confirmed inventory availability (1195 Pcs), and achieves ROHS3 compliance compared to the non-compliant status of the original part. These factors support long-term supply chain reliability and regulatory alignment for new production runs.

Selection between these parts should be based on availability requirements and regulatory compliance mandates for the target application.

Frequently Asked Questions (FAQ)

Q: Can the SY89312VMG-TR replace the SY89313VMI-TR in existing designs?

A: Yes. Both parts are parametrically equivalent with identical frequency rating (4GHz), signal types (ECL/PECL), supply voltage (3V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and package configuration (8-VFDFN, 8-MLF®). No circuit redesign is required.

Q: What is the primary difference between these two parts?

A: The SY89312VMG-TR is currently in active production status with available inventory, while the SY89313VMI-TR is discontinued. Additionally, the SY89312VMG-TR meets ROHS3 compliance requirements, whereas the original part does not.

Q: Are the package dimensions identical?

A: Yes. Both components use the 8-VFDFN Exposed Pad package in 8-MLF® (2x2) configuration, ensuring identical PCB footprint and mounting requirements.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these parts be used interchangeably in high-frequency applications?

A: Yes. Both parts support identical maximum frequency of 4GHz and maintain the same ECL/PECL signal integrity specifications required for high-speed timing applications.
