9FGV1004BQ551LTGI

Overview

The Renesas 9FGV1004BQ551LTGI is a programmable PhiClock generator from the 9FGV1004C family, designed for high-performance timing applications. It features four differential output pairs supporting LP-HCSL and LVDS signaling standards, alongside two LVCMOS reference outputs. The device operates with a 50 MHz crystal input and supports integer frequencies of 50, 100, 125, and 156.25 MHz. It complies with PCIe Gen1 through Gen4 jitter specifications, offering typical RMS phase jitter of 267 fs at 156.25 MHz (12 kHz–20 MHz). Powered by 1.8 V or 3.3 V supplies, it is housed in a compact 4.0 x 4.0 mm 24-VFQFPN or 24-LGA package.

Feature Summary

• PCIe Gen1–4 compliant with 267 fs RMS typical phase jitter at 156.25 MHz
• Four programmable differential output pairs (LP-HCSL/LVDS) plus two LVCMOS reference outputs
• Factory-configurable via OTP with hardware select pins or I²C software control
• Supports 50 MHz integrated crystal option and spread-spectrum input

Applications

• PCI Express (Gen1–Gen4) clock generation
• High-speed data communication systems
• Server and storage infrastructure timing
• Industrial equipment requiring precise clock distribution

Procurement Notes

Verify the specific suffix 'LTGI' against the manufacturer's official documentation to confirm the exact packaging type (Reel vs. Tray) and moisture sensitivity level. Factory-configured parts require matching the internal configuration settings to the application requirements before procurement. Check RoHS compliance status directly with the supplier.

Selection Notes

Select this component when PCIe Gen1–4 jitter performance is required with flexible output voltage options. Ensure the design utilizes either the 1.8 V or 3.3 V core supply correctly. Verify that the factory-programmed frequency outputs (50/100/125/156.25 MHz) match the target system needs, as these are not field-reconfigurable without reprogramming tools.

Part Context

This part belongs to the Renesas PhiClock™ 9FGV1004C series, which includes variants like the 9FGV1004CQ501LTGI. These devices share common architectural features such as the 24-lead LGA/VFQFPN packages and I²C configurability. The 'BQ' and 'LTGI' suffixes denote specific pinout, packaging, and environmental compliance variations within the broader product line.

Replacement Considerations

Direct substitutes include other 9FGV1004C family members such as the 9FGV1004CQ501LTGI, provided the factory configuration matches the application's frequency and protocol requirements. Cross-model replacements must be verified for identical package dimensions and electrical characteristics.
