Skyworks Solutions introduced a family of PCIe Gen3 buffers specifically targeting customers using Intel Xeon CPU platforms in 2014, primarily for server, storage, and datacenter. This family of products is slightly differentiated from the existing portfolio, because to participate in this business one has to be an approved supplier by Intel. Intel writes the specifications, which they refer to as white-cover or yellow-book. End customers will only use these devices if they have been approved by Intel.
