9FGL1216AGLFT

Overview

The 9FGL1216AGLFT is a high-performance clock buffer and generator designed for PCIe Gen 3, 4, and 5 applications. It features two differential LP-HCSL outputs with integrated terminations for 85Ω and 100Ω systems, eliminating the need for external resistors. The device supports Common Clocked (CC) and Separate Reference Independent Spread (SRIS) architectures, offering flexible spread spectrum options including -0.5% and -0.25% via SMBus. It operates on a single 3.3V supply and includes an open-drain CC_IR output to indicate PCIe clock mode.

Feature Summary

• Integrates internal termination resistors for both 85Ω and 100Ω systems to reduce component count
• Supports multiple PCIe clocking architectures including CC and SRIS with selectable spread spectrum
• Provides dedicated OE# pins for each output to manage CLKREQ# functionality
• Includes an open-drain status output to indicate active PCIe clock mode

Applications

• PCIe Gen 3, 4, and 5 host bridges and switches
• High-performance computing servers
• NVMe storage controllers
• Networking accelerators

Procurement Notes

Verify the specific suffix 'AGLFT' against the manufacturer's current datasheet to confirm package type and tape-and-reel configuration. Ensure the design supports the required 3.3V supply voltage and LP-HCSL signaling levels. Confirm that the selected spread spectrum settings align with system jitter requirements.

Selection Notes

Select this component when designing for PCIe Gen 3 through Gen 5 interfaces requiring low additive jitter and flexible clock architecture support. It is suitable for designs needing integrated output terminations to save board space. Consider its SMBus configurability if dynamic spread spectrum adjustment is required for EMI reduction.

Part Context

This part belongs to Renesas' intelligent clock buffer and generator family tailored for high-speed serial interfaces. It complements other devices in the series by providing robust signal integrity for PCIe standards. The device is engineered to meet the stringent timing and power efficiency demands of modern data center and enterprise infrastructure.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product family that may offer updated specifications or availability. Verify that any substitute maintains compatibility with the target PCIe generation and supported output signaling types.
