PI6CB33x Gen 4/5 Compliant Clock Buffers Diodes Incorporated PI6CB33x Gen 4/5 Compliant Clock Buffers offer an ideal clock solution for data centers, servers, storage, and network applications where the PCIe interface is used. The PI6CB33x Clock Buffer series includes 2-output, 4-output, 6-output, 8-output, and 20-output devices. The PI6CB33x Clock Buffers support High-Speed Current Steering Logic (HCSL) outputs with on-chip terminations for driving either 85 or 100 transmission lines. The on-chip termination eliminates the need for external resistors, simplifying PCB layout and reducing the bill of materials (BOM). The PI6CB33x Clock Buffers also provide Output Enable (OE) pins for each output, providing easier power management.
