9FGV1004B116NBGI8

Overview

The Renesas 9FGV1004B116NBGI8 is a programmable PhiClock generator in the 9FGV1004 family, designed for low phase-noise and low-power applications. It supports PCIe Gen1 through Gen4 compliance with typical RMS phase jitter of 267fs at 156.25MHz (12kHz–20MHz bandwidth). The device provides four programmable differential output pairs supporting LP-HCSL or LVDS signaling, alongside two LVCMOS reference outputs. Operating frequencies range from 1MHz to 325MHz for integer outputs and up to 200MHz for LVCMOS core outputs. It features individual 1.8V to 3.3V VDDO supply options per output pair.

Feature Summary

• PCIe Gen1–4 compliant with 267fs typical RMS phase jitter at 156.25MHz
• Four programmable differential output pairs plus two LVCMOS reference outputs
• Supports LP-HCSL, LVDS, and LVCMOS I/O standards with individual voltage selection
• Factory-configurable via OTP with hardware select pins or I²C software control

Applications

• PCI Express timing solutions
• High-speed data communication systems
• Server and storage infrastructure clocking

Procurement Notes

Verify the specific factory configuration encoded in the 'B116' suffix against the official datasheet or custom configuration tool, as this part is factory-configured. Confirm package details correspond to the NBGI designation (24-VFQFPN) and check current availability status with authorized distributors, as lead times may vary based on production schedules.

Selection Notes

Select this component when designing for PCIe Gen1–4 interfaces requiring low jitter performance. Ensure the required output frequency falls within the supported ranges (1MHz–325MHz for differential, 1MHz–200MHz for LVCMOS). Verify that the system power budget accommodates the typical 125mW consumption and that the 4x4mm 24-VFQFPN package fits the PCB layout constraints.

Part Context

This model belongs to the Renesas PhiClock™ programmable clock generator family, specifically the 9FGV1004 series. It is an evolution of IDT's clock generation technology acquired by Renesas. The 'B116' suffix indicates a unique factory-programmed configuration stored in One-Time Programmable (OTP) memory, distinguishing it from generic variants like the base 9FGV1004.

Replacement Considerations

Generic replacements within the 9FGV1004 family (e.g., 9FGV1004CQ501LTGI8) require reconfiguration via external EEPROM or I²C if they are not pre-programmed. Direct pin-to-pin substitutes must match the 24-VFQFPN package and support the same LP-HCSL/LVDS output standards.
