Business Combinations [Abstract]
Acquisition of Mellanox Technologies, Ltd.	Acquisition of Mellanox Technologies, Ltd.On March 10, 2019, we entered into an Agreement and Plan of Merger, or the Merger Agreement, with Mellanox Technologies Ltd., or Mellanox, pursuant to which we will acquire all of the issued and outstanding common shares of Mellanox for $125 per share in cash, representing a total enterprise value of approximately $6.9 billion as of the date of the Merger Agreement. In June 2019, Mellanox shareholders approved the acquisition. The closing of the acquisition is subject to approval by regulatory agencies. If the Merger Agreement is terminated under certain circumstances involving the failure to obtain the required regulatory approvals, we could be obligated to pay Mellanox a termination fee of $350 million. We have received regulatory approval in the United States and Mexico and are engaged with regulators in Europe and China. Although discussions with the European Union and China regulatory bodies are progressing and closing the acquisition is possible by the end of this calendar year, we believe the closing will likely occur in the early part of calendar 2020.
