Key Parameters

Substitute Part Grouping Explanation

Substitution of the 82V3155PVG8 is determined by the following critical parameters:

• Functional Purpose: Both parts must support Ethernet, SONET/SDH, and Stratum timing applications
• PLL Architecture: Both parts must incorporate PLL functionality for clock generation
• Output Capability: Both parts must provide CMOS, LVDS, or compatible output formats
• Supply Voltage Compatibility: Operating voltage ranges must overlap or be compatible with system requirements
• Operating Temperature Range: Must maintain -40°C to 85°C operation for industrial applications
• Regulatory Compliance: REACH and ECCN classifications must be equivalent or compliant
• Moisture Sensitivity: MSL rating must be acceptable for manufacturing processes

The 82P33714ANLG8 qualifies as a manufacturer-recommended substitute based on these criteria, despite differences in package type, frequency capability, and input-to-output ratio.

Parameter Comparison

Engineering Selection Recommendations

The 82P33714ANLG8 is designated as the manufacturer-recommended substitute for the obsolete 82V3155PVG8. Both devices are manufactured by Renesas Electronics Corporation and share identical operating temperature ranges (-40°C to 85°C), moisture sensitivity ratings (MSL 1), and regulatory compliance status (REACH Unaffected, ECCN EAR99).

The substitute part offers active product status, ensuring long-term availability and manufacturing support. Both devices maintain equivalent PLL functionality and support the core Ethernet, SONET/SDH, and Stratum timing applications required for WAN clock generation.

Output format compatibility is maintained through CMOS and LVDS support in both parts. The substitute provides PECL output capability in addition to CMOS and LVDS, offering expanded output format options compared to the original part's TTL support.

Supply voltage requirements differ between the parts: the original operates at 3V to 3.6V, while the substitute supports 1.8V and 3.3V operation. System integration must account for this voltage specification change during design migration.

Frequently Asked Questions (FAQ)

Q: Can the 82P33714ANLG8 directly replace the 82V3155PVG8 in existing designs?

A: Direct replacement requires verification of package compatibility and supply voltage requirements. The original part uses a 56-BSSOP package, while the substitute uses a 72-VFQFN package. PCB layout modifications are necessary. Additionally, the substitute operates at 1.8V and 3.3V, whereas the original requires 3V to 3.6V supply voltage.

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

A: Both parts provide PLL-based clock generation for Ethernet, SONET/SDH, and Stratum applications. The substitute supports higher maximum frequency (650MHz versus 32.768MHz) and offers PECL output in addition to CMOS and LVDS formats. The input-to-output ratio differs: 2:12 for the original versus 6:10 for the substitute.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both parts maintain REACH Unaffected status and EAR99 ECCN classification. Both have MSL 1 (Unlimited) moisture sensitivity ratings, suitable for standard manufacturing processes.

Q: Why is the original part classified as obsolete?

A: The 82V3155PVG8 is no longer in active production. The 82P33714ANLG8 represents Renesas Electronics Corporation's current-generation alternative for equivalent timing applications, offering enhanced capabilities and ongoing manufacturing support.

Q: What considerations apply to package migration?

A: The original 56-BSSOP package (0.295" width, 7.50mm) differs from the substitute's 72-VFQFN package (10x10mm with exposed pad). PCB redesign, thermal management evaluation, and signal integrity analysis are required for successful migration.
