Clock Buffers, Drivers Procurement Notes

Verify the #KB0 suffix indicates reel packaging with a factory quantity of 2500 units. Confirm RoHS compliance status through official documentation. Check current availability as distribution channels may report limited stock. Ensure the operating temperature range of -40°C to +105°C matches system requirements.

Clock Buffers, Drivers Selection Notes

Select this component for designs requiring PCIe Gen6 compatibility with low jitter performance. The 1.8V core voltage suits modern low-power architectures. Consider the 48-pin VFQFPN package for space-constrained PCB layouts. Verify input signal compatibility with LVDS or HCSL sources before integration.

Clock Buffers, Drivers Part Context

This part belongs to the RC193xx series of clock multipliers and buffers. It is functionally related to other variants like the RC19308A001GNA#BB0, differing primarily in packaging format. The RC19308A-EVB serves as an evaluation tool for this family. It represents an evolution in Renesas' PCIe clocking solutions, offering backward compatibility with earlier generations.

Clock Buffers, Drivers Replacement Considerations

The RC19308A001GNA#KB0 is a verified alternative within the same series, sharing identical electrical specifications but potentially differing in manufacturing lot details. Both parts utilize the 48-VFQFPN package and support the same 2:8 mux functionality. Verify pin-to-pin compatibility and software configuration settings when substituting.
