Key Parameters

Substitute Part Grouping Explanation

Substitution of the 82V3155PVG is determined by the following critical parameters:

• PLL Functionality: Both the main part and substitute must include integrated PLL capability for clock generation and frequency synthesis.
• Application Domain: Primary support for Ethernet, SONET/SDH, and Stratum timing applications.
• Output Formats: Compatibility with CMOS, LVDS, and/or PECL output standards.
• Operating Temperature Range: Maintenance of -40°C to 85°C operational envelope.
• Supply Voltage Compatibility: The substitute must operate within specified voltage ranges suitable for the target system.
• Mounting Technology: Surface mount configuration required for PCB integration.

The 82P33714ANLG qualifies as a manufacturer-recommended substitute based on these parameters, despite differences in package type, maximum frequency capability, and input/output ratio specifications.

Engineering Selection Recommendations

The 82P33714ANLG is designated as the manufacturer-recommended substitute for the obsolete 82V3155PVG. Selection of this substitute is supported by the following factors:

• Product Status Alignment: The substitute is in active production status, ensuring long-term availability and supply chain continuity.
• Functional Equivalence: Both devices provide PLL-based clock generation with support for Ethernet, SONET/SDH, and Stratum applications.
• Compliance Continuity: Both parts maintain the same operating temperature range (-40°C to 85°C), ensuring thermal compatibility with existing system designs.
• Manufacturer Endorsement: Renesas Electronics Corporation has formally identified this part as the recommended replacement, indicating functional and electrical compatibility within the specified application domain.

Design integration requires evaluation of package differences (56-BSSOP versus 72-VFQFN), supply voltage options (3V-3.6V versus 1.8V/3.3V), and maximum frequency capability (32.768MHz versus 650MHz) within the context of specific system requirements.

Frequently Asked Questions (FAQ)

Q: Why is the 82V3155PVG classified as obsolete? A: The 82V3155PVG has reached end-of-life status in Renesas Electronics Corporation's product portfolio. The 82P33714ANLG represents the current-generation replacement within the same functional category.

Q: What are the primary differences between the 82V3155PVG and 82P33714ANLG? A: Key differences include package type (56-BSSOP versus 72-VFQFN), maximum frequency capability (32.768MHz versus 650MHz), input/output ratio (2:12 versus 6:10), differential input support (No versus Yes), and supply voltage options (3V-3.6V versus 1.8V/3.3V).

Q: Can the 82P33714ANLG be used as a direct pin-for-pin replacement? A: No. The substitute uses a different package type (72-VFQFN versus 56-BSSOP) and has a different pin count (72 versus 56). PCB layout and routing modifications are required for integration.

Q: Are both parts suitable for T1/E1/OC3 applications? A: The 82V3155PVG explicitly supports T1/E1/OC3 applications. The 82P33714ANLG supports Ethernet, SONET/SDH, and Stratum applications. Application-specific compatibility must be verified against detailed datasheets and system requirements.

Q: What supply voltage should be used with the 82P33714ANLG? A: The 82P33714ANLG operates at 1.8V or 3.3V. System design must accommodate this voltage requirement, which differs from the 82V3155PVG's 3V-3.6V specification.

Q: Is the 82P33714ANLG available in production quantities? A: Yes. The 82P33714ANLG is in active production status with documented inventory availability, ensuring supply chain reliability for new designs and production builds.
