PCI Express (PCIe) Clock Buffers
Silicon Labs offers a portfolio of PCI Express Gen1/2/3/4/5 compliant low-power fanout buffer and PCI Express Gen 1/2/3 compliant zero-delay buffers. The family is ideal for consumer, industrial, server, storage, and data center applications requiring a high number of PCI Express clocks.
Our clock buffer devices feature low-power, push-pull output buffer technology, providing benefits of low-power consumption, reduced external terminating resistors, and small packaging.
