9ZXL1930EKILF

Overview

The 9ZXL1930EKILF is a low-power differential buffer derived from the Intel DB1900Z specification, manufactured by Renesas Electronics. It features 19 Low-Power HCSL (LP-HCSL) differential outputs and accepts an HCSL input clock. The device operates on a nominal 3.3V supply with separate VDDIO for outputs to optimize power consumption. Key electrical parameters include a cycle-to-cycle jitter of less than 50ps, output-to-output skew under 85ps, and fixed 0ps input-to-output delay via a fixed external feedback path. It supports PCIe Gen 1/2/3 and QPI/UPI applications up to 9.6GT/s.

Feature Summary

• Fixed feedback path providing 0ps input-to-output delay
• 19 LP-HCSL differential output pairs
• SMBus interface with 9 selectable addresses
• Spread spectrum compatible for EMI reduction

Applications

• Buffer for Romley, Grantley, and Purley Servers
• PCI-Express Gen 1/2/3 clock distribution
• QPI/UPI applications requiring low drift

Procurement Notes

Verify the ordering suffix 'EKILF' against official documentation to confirm package type, temperature range, and RoHS compliance status. Ensure the specific revision matches design requirements as suffixes may indicate manufacturing changes without altering core functionality.

Selection Notes

Select this component for designs requiring high fan-out with strict timing constraints. The fixed feedback loop minimizes drift for critical QPI/UPI interfaces. Verify that the board layout supports the required 72-pin MLF package dimensions and thermal dissipation needs for 19 active outputs.

Part Context

This part is a derivative of the IDT 9ZXL1930B, representing a low-power version of the original DB1900Z buffer. It serves as a pin-compatible upgrade offering improved phase jitter performance while maintaining compatibility with legacy server architectures.

Replacement Considerations

The datasheet identifies the 9ZXL1930B as the predecessor device. No other direct replacement part numbers are documented in the provided source material.
