PCI Express (PCIe) Clock Buffers

PCI Express Gen1/2/3/4/5 compliant low-power fanout buffers in both industrial and automotive Grade2 temperature grades are ideal for data center, automotive, industrial, and consumer applications.

Our PCI Express clock buffers feature low-power, push-pull output buffer technology, providing benefits of low-power consumption, reduced external termination resistors and small packages.
