9ZXL1951ANHGI8

Overview

The 9ZXL1951ANHGI8 is a high-performance zero-delay buffer (ZDB) from the Renesas 9ZXL1951 series. It functions as a differential clock buffer designed for critical timing applications. The device accepts HCSL input signals and generates LP-HCSL outputs with an output impedance of 85Ω, eliminating the need for external termination resistors. It supports PCIe Gen 1 through 5 compliance and features selectable PLL bandwidth to minimize jitter peaking in cascaded topologies. The component includes spread spectrum compatibility for EMI reduction and offers hardware or SMBus control for mode changes without power cycling.

Feature Summary

LP-HCSL outputs with 85Ω Zout eliminate external termination resistors
PCIe Gen 1–5 compliant with selectable PLL bandwidth
Spread spectrum compatible for EMI reduction
Hardware/SMBus control allows mode changes without power cycle

Applications

Servers and High-Performance Computing
NVMe Storage Systems
Networking Accelerators
Industrial Control Systems

Procurement Notes

Verify the specific suffix 'I8' against official Renesas documentation to confirm temperature range and packaging details. Ensure the GQFN-80 package matches the target PCB footprint. Confirm moisture sensitivity level requirements before procurement.

Selection Notes

Select this component for designs requiring low drift in QPI/UPI applications due to its fixed external feedback mechanism. Compare phase jitter performance against previous generations like the 9ZXL1950B if upgrading existing designs. Ensure the 3.3V supply voltage aligns with system power rails.

Part Context

The 9ZXL1951A is part of the second-generation enhanced-performance DB1900Z derivative family. It serves as a pin-compatible upgrade to the 9ZXL1950B, offering improved phase jitter performance while maintaining compatibility with legacy board layouts.

Replacement Considerations

The 9ZXL1950B is a confirmed pin-compatible predecessor. Verify that the improved jitter specifications of the 9ZXL1951A do not require layout adjustments compared to the older model.
