• Zero-delay buffer mode capability for low jitter performance
• HCSL input and LP-HCSL output signaling compatibility
• Operates within a 3.135V to 3.465V supply voltage range

Applications

• PCI Express riser cards
• NVMe storage systems
• Networking accelerators
• Industrial control and embedded systems

Procurement Notes

Verify the specific suffix 'BK' versus 'AK' when sourcing replacements, as manufacturing revisions may affect pinout or electrical characteristics. Confirm RoHS3 compliance status through official datasheets. Check for End-of-Life (EOL) notifications from Renesas to ensure long-term availability for production cycles.

Selection Notes

Select this component for designs requiring an 8-output distribution network for PCIe clocks. Ensure the design accommodates the 48-VFQFPN footprint. Verify that the system power supply strictly maintains the 3.135V to 3.465V range to guarantee proper operation of the internal buffers.

Part Context

This part belongs to the 9DBU series of zero-delay clock buffers from Renesas. It serves as a fanout buffer for high-speed serial interfaces. The device is often used in conjunction with main clock generators to distribute reference clocks to multiple PCIe endpoints while maintaining signal integrity.
