9FGV1004BQ551LTGI8

Overview

The 9FGV1004BQ551LTGI8 is a programmable PhiClock generator from Renesas Electronics, designed for high-performance clock distribution. It features four differential output pairs supporting LP-HCSL and LVDS signaling standards. The device accepts spread spectrum input and supports PCIe Gen1 through Gen4 jitter compliance. It operates with core voltages of 1.8V or 3.3V and includes an integrated 50MHz crystal option. The component is housed in a compact 4.0 x 4.0 mm 24-LGA package.

Feature Summary

• PCIe Gen1–4 compliant with typical phase jitter of 267fs RMS at 156.25MHz (12kHz–20MHz)
• Four programmable output pairs plus two LVCMOS reference outputs
• Supports integer, fractional, and spread-spectrum output configurations
• Factory configurable via OTP with I²C software selection capability

Applications

• PCI Express (Gen1–Gen4) clock generation
• Server and storage system timing
• High-speed data communication interfaces

Part Context

This part belongs to the 9FGV1004C-9FGV1008C family of effective programmable PhiClock generators. These devices are factory-configured units that utilize OTP memory to store user-defined clock configurations, allowing for flexible deployment without external configuration components during operation.

Replacement Considerations

Direct replacements within the same family include the 9FGV1004CQ501LTGI8 and 9FGV1004B207NBGI. Verify specific output frequencies and package variants when substituting.
