9FG1200AK-7LF

Overview

The 9FG1200AK-7LF is a low-jitter clock generator IC manufactured by Renesas Electronics Corporation. It is designed to provide precise timing signals for synchronizing high-speed data paths in server and storage applications. The device features a single crystal input and multiple differential outputs, optimized for Intel CPU server environments. It operates within a supply voltage range of 3.135V to 3.465V and supports frequencies up to 400MHz. The component is housed in a 40-VFQFN package with exposed pad, measuring 6x6 mm, suitable for surface mount installation.

Feature Summary

• Generates low-jitter clock signals essential for high-speed data synchronization
• Optimized specifically for Intel CPU server and storage system applications
• Integrates PLL functionality for stable frequency generation from crystal input

Applications

• Intel CPU server systems
• High-speed storage controllers
• Data path synchronization circuits

Procurement Notes

Verify the exact suffix '7LF' against official Renesas documentation to confirm lead-free compliance and specific package variant. Confirm current status as obsolete or end-of-life through authorized distributors. Ensure compatibility with existing board layouts due to the specific 40-VFQFN footprint. Request updated replacement part numbers if this component is no longer available for new production designs.

Selection Notes

Select this component when designing for Intel-based server architectures requiring precise clock distribution. Consider the 400MHz maximum frequency and 3.3V nominal supply requirements. Evaluate thermal performance given the exposed pad QFN package. Verify that the single-input to multi-output configuration matches the system's clock tree topology needs.

Part Context

This part belongs to Renesas' 9FGP/9FG series of clock generators, widely used in enterprise computing. These devices are engineered to meet stringent jitter specifications for modern processors. The 9FG1200AK-7LF represents a specialized solution for server-grade timing, distinct from general-purpose consumer electronics clocks.

Replacement Considerations

Official sources list the 9FG1200AK-7LFT as an alternative package type (Tape & Reel). No other direct functional substitutes are confirmed in public documentation. Designers should consult Renesas for cross-reference options if the 7LF variant is unavailable.
