9FGV1004B000NBGI8

Overview

The 9FGV1004B000NBGI8 is a programmable clock generator from Renesas Electronics' PhiClock family, housed in a 24-lead VFQFPN package. It provides four differential output pairs supporting LP-HCSL and LVDS signaling standards. The device operates on a core voltage of 1.71 V to 3.465 V with individual I/O supply options. It supports integer frequencies up to 325 MHz and accepts spread-spectrum inputs. Key electrical parameters include a maximum input frequency of 240 MHz, a typical phase jitter of 267 fs RMS at 156.25 MHz (12 kHz–20 MHz), and a duty cycle of up to 60%. The component functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• PCIe Gen1 through Gen4 compliant with low phase jitter performance
• Four programmable output pairs with selectable LP-HCSL or LVDS signaling
• Supports hardware selection via select pins or software configuration via I²C
• Integrated crystal option supported for 50 MHz input frequencies

Applications

• PCI Express interface timing solutions
• High-speed data communication systems
• Industrial equipment requiring precise clock generation

Procurement Notes

Verify the specific suffix 'NBGI8' against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm current lifecycle status as availability may vary by region. Ensure compatibility with existing PCB footprint designs for the 24-VFQFPN package before procurement.

Selection Notes

Select this component when designing systems requiring multiple synchronized clock outputs with low jitter. Verify that the required output frequency falls within the 1 MHz to 325 MHz range. Ensure the system power budget accommodates the 1.71 V to 3.465 V operating voltage. Consider I²C addressability if multiple devices are used on the same bus.

Part Context

This part belongs to the 9FGV1004 series of programmable clock generators. It shares architectural similarities with other PhiClock devices but is distinguished by its specific output count and signaling capabilities. The 'B' variant typically denotes specific factory configurations or revisions within the broader product line.

Replacement Considerations

Direct replacements must match the 24-VFQFPN package and support LP-HCSL/LVDS outputs. Check for equivalent jitter specifications and I²C configurability. Verify thermal performance and operating temperature ranges align with the original design requirements.
