9FGV1001BQ508LTGI8

Overview

The 9FGV1001BQ508LTGI8 is a programmable PhiClock generator from Renesas Electronics, designed for high-performance clock distribution. It features four differential LP-HCSL outputs and two crystal reference inputs. The device supports input frequencies of 50 MHz and provides output frequencies including 50 MHz, 100 MHz, 125 MHz, 156.25 MHz, 161.1328125 MHz, 312.5 MHz, and 322.265625 MHz. It operates on a single 1.8 V or 3.3 V supply with typical power consumption of 200 mW. The component is housed in a 24-lead LGA package (4.0 x 4.0 x 1.4 mm) and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Four differential LP-HCSL outputs with low phase jitter suitable for PCIe Gen1 through Gen5 applications
• Factory-configurable OTP memory allowing hardware selection via select pins or software configuration via I²C
• Supports multiple standard output frequencies including 100 MHz, 125 MHz, and 156.25 MHz
• Compact 24-lead LGA package (4.0 x 4.0 mm) with exposed pad for thermal management

Applications

• PCI Express (Gen1 to Gen5) reference clock generation
• High-speed serial link clock distribution
• Server and storage system clocking
• Networking equipment requiring precise timing

Procurement Notes

Verify the specific suffix LTGI8 indicates tape and reel packaging when ordering. Confirm the exact frequency configuration required, as this is a factory-programmable device. Check current availability status as lead times may vary. Ensure compatibility with existing PCB footprint for the 24-LGA package. Validate moisture sensitivity level handling procedures during assembly.

Selection Notes

Select this model if four matched differential LP-HCSL outputs are required for symmetric clock distribution. Compare against other 9FGV1001 variants based on specific output frequency needs such as 100 MHz or 125 MHz. Consider the 1.8 V core voltage requirement for low-power designs. Evaluate the I²C configurability if dynamic frequency changes are needed versus fixed OTP configuration.

Part Context

This part belongs to the Renesas PhiClock™ family of programmable clock generators. The 9FGV1001 series is optimized for meeting strict jitter budgets of modern high-speed interfaces like PCIe. It replaces discrete oscillator solutions by integrating PLL functionality and multiple output drivers into a single compact package.

Replacement Considerations

Direct pin-to-pin replacements within the 9FGV1001 family depend on matching the output frequency and package type. Verify that alternative parts support the same LP-HCSL signaling and jitter specifications. Cross-reference with Renesas documentation for updated lifecycle status.
