9FGV1004B121NBGI8

Overview

The 9FGV1004B121NBGI8 is a programmable PhiClock generator manufactured by Renesas Electronics. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 24-pin LGA package with dimensions of 4.0 x 4.0 x 1.4 mm. The device supports core supply voltages of 1.8V or 3.3V. It features six outputs, including four differential LP-HCSL and LVDS signals. The component accepts a 50 MHz crystal input frequency and generates specific output frequencies such as 50 MHz, 100 MHz, 125 MHz, and 156.25 MHz. It exhibits a maximum common-clock peak-to-peak jitter of 50 ps.

Feature Summary

• Programmable architecture supporting hardware selection via select pins or software configuration through I²C interface.
• Six-output configuration providing four differential outputs (LP-HCSL/LVDS) and two single-ended copies.
• Compliance with PCIe Gen1, Gen2, Gen3, and Gen4 jitter specifications.
• Support for spread spectrum input acceptance.

Applications

• PCI Express timing solutions
• High-speed digital system clock generation
• Industrial communication equipment

Part Context

This component belongs to the 9FGV1004C-9FGV1008C family of low phase-noise, low-power programmable clock generators originally developed by IDT and integrated into Renesas Electronics' portfolio. The 'NBGI8' suffix indicates a lead-free RoHS-compliant variant packaged in a tape and reel format suitable for automated surface-mount assembly.

Replacement Considerations

Direct replacements include other members of the PhiClock family such as the 9FGV1001, 9FGV1002, 9FGV1003, 9FGV1005, 9FGV1006, 9FGV1007, and 9FGV1008 series. Selection depends on matching the required output count, signal type (LVDS vs HCSL), and specific frequency configurations.
