5V9351PFI-G

Overview

The 5V9351PFI-G is a PLL-based clock driver manufactured by Rochester Electronics, LLC. It belongs to the 5V series and features nine true outputs with no inverted outputs. The device operates within a temperature range of -40°C to 85°C and supports operation at both 5V and 3.3V supply voltages. It utilizes a differential multiplexer for input regulation and provides three-state output characteristics. The component is housed in a TQFP-32 package (also designated as PQFP32) containing 32 terminals. This part represents a sustainment version of the Integrated Device Technology (IDT) original design.

Feature Summary

• PLL-based clock driver architecture
• Nine true outputs with three-state capability
• Dual voltage operation: 5V and 3.3V
• Differential multiplexer input regulation

Applications

• Clock distribution in high-speed digital systems
• Timing synchronization in telecommunications equipment
• Data acquisition system clock generation

Procurement Notes

Verify that the specific lot date code and manufacturing origin align with project requirements when sourcing from secondary distributors. As a sustainment product, availability may vary compared to active production lines. Confirm the package marking matches the TQFP-32 specification and ensure the supplier provides traceability documentation for the Rochester Electronics branding.

Selection Notes

Select this component when a nine-output clock driver with differential input selection is required for 5V or 3.3V logic families. Ensure the application environment stays within the -40°C to 85°C operating temperature range. Verify that the PCB footprint accommodates the 7mm x 7mm TQFP-32 package dimensions and that the thermal dissipation requirements are met for the specific load conditions.

Part Context

Rochester Electronics specializes in sustaining obsolete or end-of-life semiconductor products. The 5V9351PFI-G is a licensed reproduction of the IDT5V9351PFI8. While the original manufacturer is Integrated Device Technology, this specific part number indicates it is produced and distributed by Rochester Electronics to support long-term supply needs for existing designs.

Replacement Considerations

The IDT5V9351PFI8 is the direct functional equivalent and pin-compatible predecessor. When replacing, verify that the source document confirms the Rochester Electronics part is a drop-in replacement for the IDT original in terms of electrical parameters and mechanical footprint.
