Renesas 580G-01LF Clock Multiplexer IC Equivalent & Substitute Parts

Part Overview

The Renesas 580G-01LF is a Clock Multiplexer IC designed for 2:2 clock distribution at frequencies up to 270 MHz in a 16-TSSOP surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations. The part operates across a 2.5V to 5.5V supply range and is suitable for applications requiring single-channel clock multiplexing with dual input and output configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 580G-01LF requires evaluation against the following critical parameters:

Functional Compatibility Criteria:

• Clock multiplexing capability with minimum 2:2 input:output ratio
• Maximum frequency rating equal to or exceeding 270 MHz
• Single circuit configuration
• Surface mount technology

Electrical Compatibility Criteria:

• Supply voltage range overlap or compatibility with 2.5V ~ 5.5V
• Input and output signal type compatibility
• Operating temperature range suitable for application requirements

Physical Compatibility Criteria:

• Surface mount package format
• Pin count and footprint considerations for PCB integration

The Renesas 5P1105A000NLGI qualifies as a functional substitute based on its clock generation and distribution capabilities, higher maximum frequency rating (350 MHz), and surface mount packaging. However, differences in package type, pin count, voltage range, and temperature specifications require engineering evaluation for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 580G-01LF is classified as obsolete. The 5P1105A000NLGI maintains active product status with Renesas Electronics Corporation, ensuring ongoing availability and technical support.

Compliance and Certification: The 5P1105A000NLGI carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. Both parts maintain REACH Unaffected status and EAR99 export classification.

Functional Capability: The 5P1105A000NLGI exceeds the frequency specification of the 580G-01LF (350 MHz vs. 270 MHz) and provides expanded output capability (2:4 ratio vs. 2:2 ratio). The substitute supports multiple input signal types (HCSL, LVCMOS, LVDS, LVPECL, Crystal) and output formats (HCSL, LVCMOS, LVDS, LVPECL), offering greater application flexibility.

Design Integration Factors: Package transition from 16-TSSOP to 24-VFQFN requires PCB layout modification. Supply voltage range differs (1.71V ~ 3.465V vs. 2.5V ~ 5.5V), necessitating power supply circuit evaluation. Operating temperature range expansion (-40°C ~ 85°C vs. 0°C ~ 70°C) supports broader environmental applications.

Frequently Asked Questions (FAQ)

Q: Can the 5P1105A000NLGI directly replace the 580G-01LF without PCB modifications?

A: No. The 5P1105A000NLGI uses a 24-VFQFN package versus the 16-TSSOP package of the 580G-01LF. PCB layout redesign is required, including footprint changes, trace routing, and via placement adjustments.

Q: What are the key electrical differences between these parts?

A: The supply voltage range differs significantly (1.71V ~ 3.465V for the substitute vs. 2.5V ~ 5.5V for the original). The substitute requires lower supply voltages and narrower voltage tolerance. Power supply circuit redesign may be necessary.

Q: Does the higher frequency rating of the 5P1105A000NLGI guarantee compatibility?

A: Higher frequency capability does not automatically ensure compatibility. The substitute's different input/output signal types, package configuration, and voltage requirements must align with system design specifications. Application-specific evaluation is required.

Q: What is the significance of the 2:4 ratio versus 2:2 ratio?

A: The 5P1105A000NLGI provides four output channels from two inputs, compared to two outputs from two inputs in the original part. This expanded capability may require firmware or control logic adjustments if the application expects only two outputs.

Q: Are there any moisture sensitivity concerns with either part?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity limitations. Standard handling and storage procedures apply.

Q: How does the operating temperature range affect selection?

A: The 5P1105A000NLGI supports -40°C ~ 85°C versus 0°C ~ 70°C for the original. If the application operates below 0°C or above 70°C, the substitute provides extended temperature coverage. If the application operates only within 0°C ~ 70°C, both parts are suitable for that range.
