PCI Express (PCIe) Zero-Delay Buffers

Our PCIe Zero-Delay Buffers provide up to 19-output PCIe Gen3 fanout/zero-delay buffers compliant and qualified to the Intel DB1900Z specification for server, storage and networking applications. The devices feature constant-current mode HCSL outputs, meeting PCIe Gen1/2/3 specifications. We also offer lower output count PCIe Gen3 fanout/zero-delay buffers qualified for the Intel DB800ZL and DB1200ZL specifications. All devices feature low-power, push-pull output driver technology, providing benefits of low-power consumption, reduced external terminating resistors and small packaging. PCIe Zero-Delay Buffers are ideal for server and storage applications in data centers which require a high number of PCI Express clocks.
