9FGV1006CQ505LTGI

Overview

The 9FGV1006CQ505LTGI is a PhiClock™ programmable clock generator IC manufactured by Renesas Electronics. It operates within a supply voltage range of 1.71V to 3.465V and supports maximum frequencies up to 325MHz. The device features one circuit with a 1:4 input-to-output ratio, accepting HCSL, LVCMOS, LVDS, or crystal inputs. Outputs include HCSL, LVCMOS, LVDS, and LVPECL formats. Packaged in a 16-TFLGA exposed pad (16-LGA 3x3) for surface mount installation, it functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Programmable PhiClock™ architecture with hardware or I²C configuration options
• Supports multiple output signaling standards including HCSL, LVCMOS, LVDS, and LVPECL
• Integrated PLL with spread-spectrum capability for jitter reduction
• Compact 16-LGA (3x3mm) package with exposed thermal pad

Applications

• PCI Express timing solutions
• Ethernet interface clock generation
• High-speed data communication systems
• Server and storage subsystems

Procurement Notes

Verify the specific suffix LTGI against official Renesas documentation to confirm pinout compatibility and moisture sensitivity level (MSL 3). Confirm availability status as distribution channels may report varying stock levels or end-of-life notices. Ensure ordering quantities align with manufacturer standard packaging requirements.

Selection Notes

Select this component when a single-clock source requires four distinct output formats for mixed-voltage logic interfaces. Verify that the required output frequency falls within the 325MHz maximum limit. Ensure the design accommodates the 1.71V to 3.465V supply range and utilizes the 16-TFLGA footprint with adequate thermal relief for the exposed pad.

Part Context

This part belongs to the Renesas PhiClock™ family of programmable clock generators. It shares architectural similarities with other 9FGV100x series devices but is distinguished by its specific 1:4 output ratio and factory-programmed configuration accessed via I²C or select pins. The CQ505 suffix indicates a specific factory-configured variant within this family.

Replacement Considerations

Direct replacements within the same family include the 9FGV1006A004LTGI and 9FGV1006Q550LTGI8, provided their configured output ratios and electrical parameters match the system requirements. Verify pin compatibility and software configuration tools before substitution.
