• Provides significant power consumption and board space reduction compared to standard 3.3V HCSL devices
• Features differential input and output configurations for signal integrity

Applications

• PCI Express Gen1 clock systems
• PCI Express Gen2 clock systems
• PCI Express Gen3 clock systems

Procurement Notes

Verify the specific ordering suffix and package variant against the official Renesas datasheet to ensure compatibility with design requirements. Confirm that the 1.425V to 1.575V supply voltage range aligns with the target system's power architecture. Ensure the 24-VFQFPN footprint matches the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when designing for PCIe Gen1 through Gen3 interfaces requiring low-power clock distribution. The device offers a direct replacement path for legacy 3.3V HCSL solutions, reducing overall system power and physical footprint. Consider the 200MHz maximum frequency capability and the 2:1 multiplexing ratio when evaluating timing network complexity and signal routing constraints.
