9ZXL0831EKILF

Overview

The 9ZXL0831EKILF is an 8-output low-power differential clock buffer designed for Intel DB800ZL specifications. It supports PCIe Gen 1/2/3 and QPI/UPI applications with a maximum input frequency of 400 MHz. The device operates on a single 3.3V supply (3.135V to 3.465V) and features LP-HCSL outputs. Key electrical parameters include cycle-to-cycle jitter under 50 ps, output-to-output skew under 65 ps, and input-to-output delay variation under 50 ps. It utilizes a fixed external feedback path to achieve zero-delay buffering characteristics.

Feature Summary

• 8 differential LP-HCSL outputs with hardware control via 8 OE# pins
• Fixed external feedback path ensuring 0 ps input-to-output delay drift
• Spread spectrum compatible with tracking capability for EMI reduction
• Selectable PLL bandwidth to minimize jitter peaking in cascaded topologies

Applications

• Intel QPI and UPI processor interfaces
• PCI Express Gen 1, 2, and 3 systems
• Servers and high-performance computing platforms

Procurement Notes

Verify the suffix EKILF corresponds to the tray package variant. Confirm RoHS compliance status through official Renesas documentation prior to procurement. Ensure design compatibility with the 48-VFQFPN (6x6 mm) footprint requirements.

Selection Notes

Select this component for designs requiring pin-compatible upgrades to the 9ZXL0831A with improved phase jitter performance. It is suitable for applications needing fixed feedback paths for critical QPI/UPI stability. Consider the 9ZXL0831E or 9ZXL0851E if specific performance enhancements beyond the base model are required.

Part Context

This part belongs to the 9ZXL0831 family of second-generation enhanced performance DB800ZL differential buffers. It serves as a specialized clock distribution solution within Renesas' processor clock buffer portfolio, targeting high-speed serial interface timing requirements.

Replacement Considerations

The 9ZXL0831E is a pin-compatible upgrade offering improved phase jitter performance. The 9ZXL0851E is another pin-compatible alternative with enhanced specifications. Verify electrical parameter differences before substitution.
