In 2005 the company acquired Clarity Technologies, a leading clear voice capture (CVC) business [5] and UbiNetics, a 3G wireless (WCDMA/UMTS/HSDPA) technology company. [6] In 2007, CSR acquired Nordnav, a Swedish-based GPS software company, and CPS, a Cambridge-based GPS software company producing Enhanced GPS in partnership with Motorola. [7]

In February 2009, CSR announced it was merging with SiRF, the biggest global supplier of GPS chips, in a share deal worth $136 million; [8] in July 2010, CSR announced the acquisition of Belfast-based APT Licensing Ltd. (APT) and its aptX audio technology [9] and in February 2011, CSR announced it was merging with Zoran, a video and imaging technology company. [10]

In May 2012, CSR acquired Direct Digital Feedback Amplifier (DDFA) technology, a proprietary, highly scalable digital Class-D audio amplifier technology; [11] in June 2012, CSR announced that it had acquired the MAPX (formerly MAP-X) audio product line from Trident Microsystems, Inc [12] and in July 2012, Samsung Electronics agreed to acquire CSR's mobile phone connectivity (Bluetooth and Wi-Fi) and location (GPS/GNSS) businesses and associated IP for US$310 million (£198 million). [13] As part of the deal Samsung acquired a stake of 4.9% in CSR. [13]
