9ZXL1952DNHGI

Overview

The Renesas 9ZXL1952DNHGI is a clock buffer belonging to the 9ZXL1952D series, described as a DB1900Z low-power derivative. It features 19 outputs with LP-HCSL signaling and accepts HCSL inputs. The device operates within a supply voltage range of 3.135 V to 3.465 V and supports maximum input frequencies up to 400 MHz. It is housed in an 80-pin GQFN package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• 19 differential outputs utilizing LP-HCSL signaling
• HCSL input compatibility with support for spread spectrum inputs
• Operates on a single 3.3V nominal supply (3.135V–3.465V)
• Integrated into the 9ZXL1952D family for PCIe and processor clocking

Applications

• PCIe compliant clock distribution
• Processor clock buffering
• High-performance computing systems

Procurement Notes

Verify the specific suffix 'NHGI' against official Renesas documentation to confirm exact packaging and moisture sensitivity levels. Ensure the component meets RoHS requirements for the target assembly process. Cross-reference the Mouser part number 972-9ZXL1951DNHGI if the exact 9ZXL1952DNHGI datasheet is unavailable, as naming conventions may vary across distributor listings.

Selection Notes

Select this component when a high-output count (19) is required for fanout applications. The LP-HCSL output type is suitable for low-voltage, low-power designs. Verify that the 400 MHz maximum frequency aligns with the system's clock requirements. The GQFN-80 package requires appropriate PCB footprint design for thermal management.

Part Context

This component is part of the Renesas 9ZXL1952D series, which serves as a low-power derivative of the legacy DB1900Z buffer. It is designed to replace older generation buffers while maintaining pin compatibility or offering improved power efficiency. The series targets modern server and storage architectures requiring dense clock distribution.

Replacement Considerations

The 9ZXL1950D is a pin-compatible upgrade within the same family, offering enhanced phase jitter performance. Designers should verify electrical parameter differences between the 9ZXL1952D and 9ZXL1950D variants before substitution.
