9FGV1004BQ53ALTGI

Overview

The 9FGV1004BQ53ALTGI is a programmable clock generator from the Renesas PhiClock family, designed for low phase-noise applications. It features four differential outputs supporting LP-HCSL and LVDS signaling standards. The device operates within a supply voltage range of 1.71 V to 3.465 V and supports output frequencies up to 325 MHz with an input frequency capability of 240 MHz. Packaged in a compact 24-VFQFPN format, it delivers typical jitter performance of 27 ps. This component is suitable for high-speed digital systems requiring precise timing signals.

Feature Summary

• Supports integer and fractional/spread-spectrum output configurations
• Low phase noise with typical jitter of 27 ps
• Operates on a single supply voltage between 1.71 V and 3.465 V

Applications

• PCI Express compliant clock generation (Gen1–Gen4)
• High-speed data communication interfaces
• Server and storage system timing solutions
• Industrial control equipment requiring precise clock synchronization

Procurement Notes

Verify the specific suffix 'BQ53ALTGI' against official Renesas documentation to confirm factory configuration details, as suffixes often denote unique programming or packaging variations. Confirm current availability status, as this part number may be subject to discontinuation or lifecycle changes. Ensure compatibility with existing board designs regarding the 24-VFQFPN package dimensions and thermal requirements before procurement.

Selection Notes

Select this component when designing systems that require flexible clock distribution with support for both LVDS and LP-HCSL standards. Consider the 24-VFQFPN package size if board space is constrained. Verify that the required output frequencies fall within the 1 MHz to 325 MHz range and that the power supply constraints align with the 1.71 V to 3.465 V operating window. Check if I2C configurability or hardware pin selection meets the design flexibility needs.

Part Context

This device belongs to the 9FGV1004 series of programmable clock generators, which are part of Renesas' broader PhiClock portfolio. The series is engineered to meet stringent jitter specifications for modern high-speed serial interfaces. Variations within the series typically differ by output count, package type, or pre-programmed frequency settings, making the specific suffix critical for identifying the exact electrical and physical characteristics of the unit.

Replacement Considerations

Direct replacements should be sought within the 9FGV1004 family or compatible PhiClock devices. Verify pin-to-pin compatibility with the 24-VFQFPN package. Ensure that any substitute part supports the same output signaling types (LP-HCSL/LVDS) and meets the required jitter specifications for the application.
