The acquisition does not include Cortina's Access and Digital Home business, which is currently scheduled to be divested prior to the acquisition close and will continue as an independent company. The transaction is expected to close in late September or October. The acquisition is expected to add an additional $20M in revenue per quarter at higher gross margins than Inphi's gross margins. The company expects 50% improvement in total quarterly operating income as a percentage of revenue on a non-GAAP basis.
