9ZXL1951ANHGI

Overview

The Renesas 9ZXL1951ANHGI is a high-performance zero-delay buffer (ZDB) from the 9ZXL1951 series. It functions as a differential clock buffer designed for critical timing applications. The component utilizes an HCSL input and provides LP-HCSL outputs with a characteristic impedance of 85Ω, eliminating the need for external termination resistors. It operates on a single 3.3V supply voltage and supports spread spectrum input clocks for EMI reduction. The device features software-controlled outputs via SMBus and selectable PLL bandwidth to minimize jitter peaking in cascaded topologies.

Feature Summary

LP-HCSL outputs with 85Ω Zout eliminate external termination resistors
SMBus OE bits allow software control of each output
Selectable PLL bandwidth minimizes jitter peaking in cascaded PLL topologies
Spread spectrum compatible; tracks spreading input clock for EMI reduction

Applications

PCIe Gen 1–5 compliant systems
Critical QPI/UPI applications requiring low drift
High-performance computing servers

Procurement Notes

Verify the specific suffix ANHGI against official documentation to confirm package details and moisture sensitivity level. Ensure compatibility with existing PCB layouts regarding the GQFN-80 package dimensions. Confirm lead-free status and RoHS compliance requirements prior to ordering.

Selection Notes

Select this component when a pin-compatible upgrade to the 9ZXL1950B is required with improved phase jitter performance. It is suitable for designs needing fixed external feedback to maintain low drift for demanding QPI/UPI applications. Consider the 72-VFQFPN footprint if board space is constrained.

Part Context

The 9ZXL1951A is part of the second-generation enhanced-performance DB1900Z derivative family. It serves as a differential buffer offering significantly improved phase jitter compared to previous generations while maintaining pin compatibility with legacy designs.

Replacement Considerations

The 9ZXL1950D is a pin-compatible upgrade option within the same family. Verify that the specific output count and package type match the original design requirements before substitution.
