9FGV1004B217NBGI

Overview

The 9FGV1004B217NBGI is a factory-configured programmable clock generator from Renesas Electronics, belonging to the PhiClock family. It provides four differential output pairs supporting LP-HCSL and LVDS signaling standards, with individual core voltage options of 1.8V or 3.3V. The device accepts integer and fractional or spread-spectrum input frequencies, delivering outputs in the range of 1MHz to 325MHz for integer modes. It features two integer-related frequency copies, one fractional or spread-spectrum copy, and two crystal reference copies per configuration. Hardware selection via select pins or software selection via I²C allows configuration flexibility, with support for up to four unique I²C addresses.

Feature Summary

• Four programmable differential output pairs with LP-HCSL or LVDS signaling
• Supports integer (1MHz–325MHz) and fractional/spread-spectrum output configurations
• Factory-configured OTP memory with hardware or I²C selection capability
• Individual 1.8V to 3.3V core voltage support for each output pair

Applications

• PCIe Gen1 through Gen4 compliant clock generation
• High-speed data communication interfaces requiring low jitter clocks
• Server and storage system timing architectures

Procurement Notes

Verify the specific suffix 'NBGI' against official Renesas documentation to confirm package type (VFQFPN-24) and lead-free status. Confirm availability and lead times directly with authorized distributors as stock levels fluctuate. Ensure the factory-programmed configuration matches the target application requirements, as post-manufacturing changes are not possible.

Selection Notes

Select this component when a fixed, pre-configured clock solution is preferred over field-programmable alternatives. Verify that the required output frequencies fall within the supported ranges for integer or fractional modes. Check compatibility with the target logic families (LP-HCSL/LVDS) and ensure the supply voltage constraints align with the system design. Consider the 24-pin VFQFPN package dimensions for PCB layout planning.

Part Context

This part is a member of the 9FGV1004 series, designed as a drop-in replacement for standard clock generators in high-performance computing applications. It integrates multiple output drivers into a compact 4mm x 4mm package, reducing board space compared to discrete solutions. The PhiClock family emphasizes low power consumption and flexible configuration options for complex timing networks.

Replacement Considerations

Direct replacements must match the 9FGV1004 electrical specifications and pinout. Verify that alternative parts support the same output signaling standards (LP-HCSL/LVDS) and voltage levels. Cross-reference the factory-programmed frequency settings with the new component's capabilities to ensure functional equivalence.
