9FGV1004B211NBGI

Overview

The Renesas 9FGV1004B211NBGI is a programmable clock generator from the PhiClock family, designed for high-performance timing applications. It features four differential outputs supporting LP-HCSL and LVDS signaling standards. The device operates within a supply voltage range of 1.71 V to 3.465 V and supports output frequencies up to 325 MHz with a maximum input frequency of 240 MHz. Key electrical specifications include a typical phase jitter of 27 ps and a duty cycle of up to 60%. It is housed in a compact 24-pin VFQFPN package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Four differential output pairs configurable for LP-HCSL or LVDS standards
• Supports integer and fractional/spread-spectrum output configurations
• Hardware selection via select pins or software control via I²C interface
• Compliant with PCIe Gen1 through Gen4 jitter requirements

Applications

• PCI Express (Gen1-Gen4) compliant systems
• High-speed data communication interfaces
• Server and storage infrastructure timing
• Industrial equipment requiring precise clock generation

Procurement Notes

This component is identified as obsolete by the manufacturer. Verification of availability should focus on secondary market distributors or surplus inventory providers. Buyers must confirm the specific manufacturing date code and physical condition of the units, as standard new production channels are no longer active for this part number.

Selection Notes

Select this model when a fixed-output configuration is sufficient without the need for external programming hardware. Ensure the design requires LP-HCSL or LVDS outputs within the 325 MHz limit. Verify that the system power supply accommodates the 1.71 V to 3.465 V operating range and that the 24-pin VFQFPN footprint matches the PCB layout constraints.

Part Context

The 9FGV1004B series belongs to Renesas' PhiClock programmable clock generator family. These devices are factory-configured to provide specific frequency outputs, eliminating the need for user-programmable EEPROM or flash memory. This variant offers four differential outputs, distinguishing it from single-output or lower-channel variants in the same product line.

Replacement Considerations

Direct replacements may be limited due to the obsolete status. Consider the 9FGV1004C series for newer designs, noting potential differences in package type (LGA vs. VFQFPN) and supported PCIe generations. Verify pin compatibility and output signaling standards before substituting.
