Exar Corporation- Interface ICs

Exar Corporation was a leading provider of high-performance analog and mixed-signal integrated circuits for communications, networking, storage, and industrial applications. Headquartered in Fremont, California, the company specialized in physical interface and access control solutions for broadband communication networks. Its product portfolio included serial transceivers, line drivers, receivers, and data converters optimized for T/E carrier and SONET/SDH applications, supporting data rates from T1/E1 to OC-192. Exar also offered power management ICs, connectivity components, and network security processors for enterprise and telecom systems. The company leveraged advanced semiconductor processes such as CMOS, BiCMOS, and bipolar technologies, with the majority of products manufactured by third-party foundries. Exar's innovative PHY and MAC layer solutions enabled the transition from voice-centric to converged voice-data networks, addressing the growing demand for higher bandwidth. Key customers included major equipment vendors like Alcatel, Cisco, Hewlett-Packard, Lucent, Nokia, and Tellabs. In addition to communication ICs, Exar provided high-speed analog front-end chips for digital imaging and video equipment, serving applications in digital cameras and medical devices. With a global presence, the company offered real-time technical support and rapid product customization to accelerate customer development cycles.
