9FGV1004B222NBGI8

Overview

The 9FGV1004B222NBGI8 is a programmable clock generator from Renesas Electronics' PhiClock family. It provides four differential output pairs supporting LP-HCSL and LVDS signaling standards, with individual VDDO supply options for 1.8V to 3.3V operation. The device accepts integer or fractional/spread-spectrum inputs within a frequency range of 1MHz to 325MHz. It features two integer-related frequencies, one fractional or spread-spectrum frequency, and two crystal reference copies per configuration. Hardware selection via select pins or I²C software control allows configuration of four OTP settings. The component operates within a -40°C to +85°C temperature range.

Feature Summary

• Four programmable differential output pairs (LP-HCSL/LVDS) with independent 1.8V-3.3V VDDO supplies
• Supports PCIe Gen1–Gen4 compliance with typical phase jitter of 267fs RMS at 156.25MHz (12kHz–20MHz)
• Configurable via hardware select pins or I²C interface with four unique addresses
• Accepts integer, fractional, and spread-spectrum input frequencies up to 325MHz

Applications

• PCIe compliant system clock generation
• NVMe SSD timing solutions
• Server and storage infrastructure clock distribution

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 varies by region and distributor. Ensure compatibility with existing design constraints regarding voltage levels and output signaling standards before procurement.

Selection Notes

Select this component when designing systems requiring multiple independent clock outputs with mixed signaling standards like LP-HCSL and LVDS. Verify that the required output frequencies fall within the 1MHz to 325MHz range. Consider the I²C configurability if dynamic clock changes are needed during operation. Ensure the 24-pin VFQFPN or LGA package fits the PCB layout constraints.

Part Context

This part belongs to the 9FGV1004 series of programmable clock generators. The series is designed for high-performance computing and storage applications. Variants in the series differ by output count, package type, and factory programming configurations. The 'B' prefix typically denotes specific electrical characteristics or revisions within the PhiClock family.

Replacement Considerations

Direct replacements include other 9FGV1004 variants with compatible output counts and signaling standards. Check datasheets for pin-to-pin compatibility and identical electrical parameters such as jitter performance and supply voltages. Ensure any substitute supports the same I²C addressability and configuration methods.
