9DBV0931AKLFT

Overview

The 9DBV0931AKLFT is a nine-output, 1.8V PCIe fanout clock buffer manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 1.7V to 1.9V and supports input frequencies from 1 MHz to 200 MHz. The device features one differential HCSL input and nine differential LP-HCSL outputs, housed in a 48-lead VFQFPN package with dimensions of 6.0 x 6.0 mm. It includes integrated terminations for direct connection to 100Ω transmission lines and offers multiple SMBus addresses for clock management.

Feature Summary

• Supports PCIe Gen1 through Gen5 jitter compliance standards
• Features integrated termination resistors for direct transmission line connection
• Includes multiple selectable SMBus addresses for advanced clock management

Applications

• PCI Express (PCIe) system clock distribution
• High-performance server and storage backplanes
• Network interface cards requiring low-jitter clocking

Procurement Notes

Verify the specific suffix 'AKLFT' against the manufacturer's current datasheet to confirm pinout and electrical specifications. Check for Product Change Notifications (PCNs) regarding assembly site changes or material updates. Confirm moisture sensitivity level (MSL) handling requirements prior to surface mount assembly to ensure component integrity during soldering processes.

Selection Notes

Select this component when a high-channel-count, low-power PCIe clock buffer is required. Ensure the design utilizes a 1.8V supply rail compatible with the specified operating range. Verify that the PCB layout accommodates the 48-lead VFQFPN package dimensions and thermal requirements. Confirm that the input source matches the HCSL signaling standard supported by the device.

Part Context

This part belongs to Renesas' comprehensive PCIe clocking family, designed specifically for high-speed serial link applications. It serves as a critical timing element in systems requiring precise clock distribution across multiple PCIe lanes. The device complements other members of the 9DBV series, offering scalable solutions for varying output counts while maintaining signal integrity standards.

Replacement Considerations

The 9DBV0941AKILF is listed as an alternative within the same product family. Verify compatibility regarding package type, pin configuration, and electrical parameters before substitution. Ensure that any replacement part meets the same PCIe generation support and jitter performance requirements.
