9FGV1006BQ536LTGI

Overview

The Renesas 9FGV1006BQ536LTGI is a programmable PhiClock generator designed for high-speed serial interface timing. It provides four spread-spectrum output pairs and two LVCMOS reference outputs, supporting PCIe Gen1 through Gen7 compliance with typical phase jitter of 276fs RMS at 156.25MHz (12kHz–20MHz). The device accepts input frequencies from 1MHz to 325MHz via crystal or LVCMOS sources. It operates with a core voltage of 1.8V to 3.3V and supports individual I/O voltages of 1.8V, 2.5V, or 3.3V per output pair. The component utilizes a 4mm x 4mm 24-LGA package.

Feature Summary

• PCIe Gen1–7 compliant with common clock jitter < 41fs RMS
• Four programmable output pairs plus two LVCMOS REF outputs
• Supports integer, fractional, or spread-spectrum frequency generation
• Configurable via hardware select pins or I²C software control

Applications

• PCI Express Gen1–Gen7 system clocking
• High-performance computing platforms
• Data center infrastructure equipment
• Telecommunications base stations

Procurement Notes

Verify the specific suffix LTGI indicates the 24-LGA package variant and lead-free status. Confirm the BQ536 configuration code matches the required output frequencies and spread-spectrum parameters. Ensure compatibility with the Timing Commander software for OTP programming if field reconfiguration is not required. Check for RoHS compliance documentation corresponding to the manufacturing date code.

Selection Notes

Select this model when PCIe Gen7 jitter specifications are mandatory. Compare against the 9FGV1002 if fewer than four differential outputs are needed. Verify that the 1MHz–325MHz input range covers the system's reference clock requirements. Consider the 24-LGA package constraints for PCB layout and thermal management compared to the VFQFPN alternative.

Part Context

This component belongs to the Renesas PhiClock™ family of programmable clock generators. It shares architectural similarities with the 9FGV1002 and 9FGV1004 but offers enhanced jitter performance suitable for next-generation PCIe standards. The family supports multiple I/O standards including LP-HCSL and LVDS.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate the 9FGV1002 or 9FGV1004 only if jitter tolerances allow for higher values. Verify pin-to-pin compatibility and electrical parameter overlaps before considering any cross-model substitution.
