9ZML1245AKILF

Overview

The 9ZML1245AKILF is a clock multiplexer manufactured by Renesas Electronics, designed for PCI Express applications. It features a 2:12 input-to-output ratio with differential HCSL inputs and LP-HCSL outputs. The device integrates a PLL capable of operating up to 400 MHz and supports spread spectrum input frequencies. It operates within a supply voltage range of 3.135V to 3.465V and functions at temperatures between -40°C and +85°C. The component is housed in a 72-VFQFPN package measuring 10x10 mm.

Feature Summary

• Integrates a low-noise PLL for jitter reduction in PCIe clocking architectures
• Supports 2:12 multiplexing with differential HCSL inputs and LP-HCSL outputs
• Compatible with PCIe Gen1 through Gen7 standards in both PLL and Bypass modes
• Spread spectrum tolerant design to assist in EMI reduction

Applications

• PCI Express (PCIe) clock distribution systems
• Server and storage infrastructure timing solutions
• High-performance computing platforms requiring precise clock synchronization

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature grade. Ensure compliance with RoHS directives as indicated in official datasheets. Confirm moisture sensitivity levels and recommended reflow profiles prior to assembly to maintain component integrity during manufacturing processes.

Selection Notes

Select this component when a 2:12 clock multiplication or distribution ratio is required for PCIe designs. The integrated PLL makes it suitable for applications needing jitter cleaning. Verify that the LP-HCSL output signaling matches the requirements of downstream logic components. Ensure the 3.3V nominal supply voltage aligns with the system power architecture.

Part Context

This part belongs to the 9ZML1245A series of Z-BUFFER MUX devices from Renesas. These components are engineered to provide flexible clock routing and conditioning for high-speed serial interfaces.
