9FGV1006BQ506LTGI

Overview

The 9FGV1006BQ506LTGI is a programmable clock generator from Renesas Electronics' PhiClock family. It provides six output pairs, including four differential outputs and two LVCMOS reference copies. The device supports integer frequencies up to 325 MHz on differential outputs (LVDS or LP-HCSL) and up to 200 MHz on LVCMOS outputs. It features factory-configurable OTP settings selectable via hardware pins or I²C software control. Key specifications include a typical phase jitter of 267 fs RMS at 156.25 MHz and compliance with PCIe Gen1 through Gen4 standards.

Feature Summary

• Six output pairs: four differential (LP-HCSL/LVDS) and two LVCMOS reference copies
• Factory-programmable configurations accessible via hardware select pins or I²C
• Supports integer frequencies up to 325 MHz (differential) and 200 MHz (LVCMOS)
• Typical phase jitter of 267 fs RMS at 156.25 MHz (12 kHz–20 MHz offset)

Applications

• PCI Express Gen1, Gen2, Gen3, and Gen4 timing solutions
• NVMe SSD clock generation for U.2 and M.2 form factors
• General-purpose programmable clock distribution in high-speed digital systems

Procurement Notes

Verify the specific suffix 'BQ506' against official Renesas documentation to confirm the exact factory configuration and pinout. Confirm package type (typically 24-LGA or VFQFPN) and moisture sensitivity level (MSL 3) prior to ordering. Ensure compatibility with existing PCB layout constraints for the selected package variant.

Selection Notes

Select this component when a fixed, factory-configured clock solution is preferred over field-programmable alternatives. Verify that the required output frequencies (up to 325 MHz) and signaling standards (LVDS/LP-HCSL) match the target system requirements. Consider the I²C addressability if multiple devices are used on the same bus.

Part Context

This part belongs to the 9FGV100x series of PhiClock programmable clock generators. Unlike fully user-programmable variants, this model utilizes factory-set One-Time Programmable (OTP) memory. The 'Q' suffix typically indicates an integrated crystal option, while 'LTGI' denotes the lead-free tape and reel packaging format.

Replacement Considerations

Direct replacements within the PhiClock family include other 9FGV100x variants with matching output counts and frequency ranges. Verify pin-to-pin compatibility and electrical parameters such as supply voltage (1.8V/3.3V) and jitter performance before substituting.
