9FGV1001CQ505LTGI

Overview

The 9FGV1001CQ505LTGI is a programmable clock generator from the Renesas PhiClock series. It features one circuit with a maximum frequency of 325MHz and a 1:6 input-to-output ratio. The device accepts HCSL, LVCMOS, LVDS, or crystal inputs and provides CML, HCSL, LP-HCSL, LVCMOS, LVDS, and LVPECL outputs. Operating on a 1.71V to 3.465V supply within -40°C to 85°C, it is housed in a 24-LFLGA (4x4mm) surface-mount package.

Feature Summary

• Programmable architecture supporting multiple output signaling standards including LP-HCSL, LVDS, and LVPECL.
• Single circuit configuration with a 1:6 input-to-output frequency ratio.
• Wide supply voltage range of 1.71V to 3.465V for flexible power integration.
• Industrial temperature rating spanning -40°C to 85°C ambient operating conditions.

Applications

• Ethernet interface clock generation
• PCI Express (PCIe) system timing

Procurement Notes

Verify the specific ordering suffix LTGI against official documentation to confirm package type and moisture sensitivity level. Ensure the selected variant matches the required output drive strength and pinout configuration for the target PCB layout. Cross-reference the manufacturer's latest datasheet for any updates regarding RoHS compliance status and recommended soldering profiles.

Selection Notes

Select this component when a single-clock source must fan out to six distinct destinations with mixed signaling requirements. Confirm that the available input frequencies align with the internal PLL multiplication factors needed for the desired 325MHz maximum output. Evaluate the thermal performance of the 24-LFLGA package to ensure adequate heat dissipation under continuous operation at high frequencies.

Part Context

This part belongs to the 9FGV1001 family of programmable clock generators designed for high-speed digital interfaces. The PhiClock series emphasizes low jitter performance and flexibility through factory-programmable configurations. The 24-LFLGA package offers a compact footprint suitable for dense board layouts in modern computing and networking equipment.

Replacement Considerations

Consult the official Renesas replacement matrix for verified cross-references. Ensure any substitute maintains the 24-LFLGA footprint and compatible electrical characteristics for direct pin-to-pin integration without schematic modification.
