9ZXL1530EKILF

Overview

The Renesas 9ZXL1530EKILF is a 15-output differential clock buffer derived from the Intel DB1900Z. It utilizes Low-Power HCSL (LP-HCSL) outputs to reduce power consumption by over 50% compared to the original IDT9ZX21501. The device features a fixed external feedback path for zero input-to-output delay, maintaining low drift for demanding QPI/UPI applications. It supports PCI Express Gen 1/2/3 and operates in PLL or bypass modes with selectable bandwidths. Key electrical parameters include a maximum cycle-to-cycle jitter of 50 ps, output-to-output skew under 65 ps, and phase jitter below 1 ps rms for PCIe Gen 3.

Feature Summary

• 15 LP-HCSL differential output pairs with integrated termination resistors
• Fixed external feedback path providing 0 ps input-to-output delay
• Supports PLL and bypass modes with selectable bandwidth to minimize jitter peaking
• Spread spectrum compatible for EMI reduction

Applications

• Buffer for Romley, Grantley, and Purley Servers
• PCI Express Gen 1/2/3 clock distribution
• QPI/UPI memory interface clocking

Procurement Notes

Verify that the ordering suffix EKILF corresponds to the specific tape and reel packaging configuration as defined by the manufacturer's current documentation. Confirm RoHS compliance status through official datasheets. Ensure the component meets the commercial temperature range specifications of 0°C to +70°C for the intended application environment.

Selection Notes

Select this component when a high-output count clock buffer with low power consumption is required for server architectures. The fixed feedback design is critical for applications needing precise timing alignment between input and output clocks. Ensure the system design accommodates the separate VDDIO supply for optimized power management and the SMBus interface for dynamic control.

Part Context

This part belongs to the 9ZXL1530 family of low-power derivative buffers. It serves as a pin-compatible upgrade to previous generations, offering improved phase jitter performance and enhanced system security features via SMBus control. The device is designed to replace older buffer solutions while reducing board space and power requirements in high-performance computing environments.
