9FGV1001B012NBGI

Overview

The 9FGV1001B012NBGI is a programmable clock generator from Renesas Electronics' 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, with four unique addresses for multi-component access. Operating within a -40°C to 85°C temperature range, it utilizes a 24-lead VFQFPN package (4.0 x 4.0 mm) and accepts HCSL, LVCMOS, LVDS, or crystal inputs.

Feature Summary

• Provides four identical non-spread-spectrum output frequencies derived from a single input source.
• Supports flexible configuration via hardware select pins or I²C software control.
• Features four distinct I²C addresses to facilitate system integration with multiple components.
• Delivers low phase jitter performance suitable for PCIe Gen1 through Gen5 compliance.

Applications

• PCI Express (Gen1, Gen2, Gen3, Gen4, Gen5) interface timing
• Ethernet network infrastructure equipment
• High-speed data acquisition systems

Part Context

This component belongs to the 9FGV1001 series, which serves as the root part for various factory-configurable variants. The 'B012' suffix indicates specific factory-programmed output frequencies and input requirements, distinguishing it from other suffixes like 'C000' or 'C012'. The 'NBGI' designation confirms the 24-lead VFQFPN package type and lead-free construction.

Replacement Considerations

Direct replacements must match the PhiClock™ 9FGV1001 architecture and the specific output frequencies programmed into the B012 variant. Verify that alternative parts support the same LP-HCSL output signaling and 1.8V core voltage requirements. Cross-reference the exact output frequencies against the target datasheet specifications to ensure signal integrity compatibility.
