9FGV1001B112NBGI8

Overview

The 9FGV1001B112NBGI8 is a programmable clock generator from the Renesas PhiClock family, designed for high-performance timing applications. It provides four non-spread-spectrum copies of a single output frequency and two copies of the crystal reference input. The device supports hardware selection via select pins or software configuration through I²C, allowing flexible deployment in systems requiring precise clock distribution. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Provides four identical non-spread-spectrum output clocks derived from a single input frequency
• Supports dual configuration methods: hardware pin selection and I²C software control
• Includes two dedicated outputs for the crystal reference input signal
• Features four unique I²C addresses to facilitate multi-device bus access

Applications

• PCI Express Gen1, Gen2, Gen3, Gen4, and Gen5 compliant systems
• High-speed data communication interfaces requiring low jitter
• Server and storage infrastructure clock distribution
• Networking equipment timing solutions

Procurement Notes

Verify the specific suffix NBGI8 against the manufacturer's current datasheet to confirm package type and reel specifications. Ensure compatibility with existing PCB footprints, as the VFQFPN-24 package dimensions are critical for assembly. Confirm moisture sensitivity level requirements before procurement to manage storage and reflow soldering conditions appropriately.

Selection Notes

Select this component when four identical non-spread-spectrum clock outputs are required alongside reference buffering. Compare against spread-spectrum variants like the 9FGV1002 series if EMI reduction is a priority rather than strict frequency stability. Verify that the target system supports the necessary I²C addressing scheme or hardware pin logic for configuration.

Part Context

This part belongs to the 9FGV1001C root family, which includes various factory-configured options. The NBGI8 suffix indicates a specific configuration variant packaged in a VFQFPN-24 form factor. It shares architectural similarities with other PhiClock generators but is distinguished by its fixed output frequency settings programmed at the factory.

Replacement Considerations

Direct replacements include other 9FGV1001C variants with matching output frequencies and LP-HCSL signaling. Cross-reference with the 9FGV1002 series only if spread-spectrum functionality is acceptable. Ensure any substitute maintains the same 24-pin VFQFPN footprint and thermal characteristics.
