9FGV1005A112LTGI8

Overview

The 9FGV1005A112LTGI8 is a programmable clock generator from the Renesas PhiClock family. It provides four spread-spectrum copies of a single output frequency and two copies of the crystal reference input. The device supports hardware selection via select pins or software selection through I²C, allowing any of four OTP configurations to be set as default in I²C mode. Four unique I²C addresses are available for multi-component access.

Feature Summary

• Programmable PhiClock Generator with 4 spread-spectrum outputs and 2 LVCMOS REF outputs
• Supports HCSL, LVDS, and LVCMOS I/O standards with individual VDDO options
• Hardware or I²C configuration with 4 unique I²C addresses
• PCIe Gen1–7 compliant with jitter < 41fs RMS

Applications

• PCI Express (PCIe) systems
• Ethernet applications
• Automotive timing circuits

Procurement Notes

Verify the specific suffix LTGI8 indicates reel packaging with a factory quantity of 2500 units. Confirm moisture sensitivity level (MSL 3) and lead-free status during procurement. Ensure I²C address settings match system requirements for multi-device configurations.

Selection Notes

Select this component when PCIe Gen1–7 compliance and low jitter (< 41fs RMS) are required. Choose based on output signaling needs: LP-HCSL/LVDS for high-speed differential signals or LVCMOS for lower frequencies up to 200MHz. Verify voltage compatibility with 1.8V to 3.3V core and individual output bank voltages.

Part Context

Part of the 9FGV1005 series within the PhiClock™ family. Shares features with 9FGV1002 and 9FGV1004 models but offers specific output counts and packaging options. Designed for high-performance timing in data center and automotive environments.

Replacement Considerations

Direct substitutes include other 9FGV1005 variants like 9FGV1005Q500LTGI or 9FGV1004CQ501LTGI8 if pinout and output configuration match. Verify I²C addressability and OTP configuration compatibility before substitution.
