9ZXL1550BKLFT

Overview

The Renesas 9ZXL1550BKLFT is a clock buffer featuring 15 LP-HCSL outputs. It operates within a supply voltage range of 3.135 V to 3.465 V and supports a maximum input frequency of 150 MHz. The device exhibits a maximum propagation delay of 4.5 ns. It is housed in a 64-pin VFQFPN package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Utilizes Low-Power HCSL (LP-HCSL) output signaling to increase edge rates
• Serves as a derivative buffer for the DB1900Z architecture
• Designed for PCIe and QPI application environments

Applications

• PCIe clock distribution
• QPI/UPI critical applications
• Processor clock buffering

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging versus the 'LF' variant which may use trays. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the 64-VFQFPN footprint matches your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when LP-HCSL outputs are required for low-power clock distribution. It serves as a suitable replacement for legacy DB1900Z designs needing increased edge rates. Consider the 150 MHz input limit and commercial temperature range against higher-performance variants like the 9ZXL1550DKILF if industrial temperatures or higher frequencies are needed.

Part Context

This part belongs to the 9ZXL1550 series, representing a low-power derivative of the DB1900Z family. It provides 15 differential outputs with fixed external feedback characteristics. The series targets high-speed serial interface clocking needs in server and storage systems requiring stable signal integrity.

Replacement Considerations

The 9ZXL1550DKILF is a documented low-power derivative variant offering extended temperature ranges (-40°C to +85°C) and higher input frequency support up to 400 MHz. Verify pin compatibility and electrical parameter differences before substitution.
