Data Compression

Mobile devices, social media, sensor-enabled e-commerce, the cloud and web 2.0 applications are transforming the global IT infrastructure. The amount and type of data or "Big Data" is changing and growing exponentially. Big Data, which now includes increasing amounts of unstructured data, needs to be available anytime, anywhere and in various formats. As a result, the IT infrastructure must be adaptive, always-on, scalable, secure and cost effective.

Exar's data compression and security solutions address the evolving IT infrastructure needs by providing high availability and performance, workload optimization, security for data in transit or at rest, storage capacity optimization (SCO) and reduced total cost of ownership (TCO).

Power Conversion

 Power ConvertionA complete family of DC to DC power conversion products from linear LDOs and regulators to high-performance switching regulators and controllers for applications with currents ranging from a few mA to 30A.

Connectivity Products

EXAR, the market leader, offers the industry's broadest line-up of UART, bridging and serial protocol transceivers solutions.

Exar offers over 100 UART devices supporting a wide operating power supply range from 1.62V to 5.5V, 1 to 384 bytes of FIFO and popular interfaces such as USB, PCIe, PCI, I2C, SPI, VLIO and 8-bit. In addition, Exar offers serial transceivers that support standards such as RS-232, RS-422 or RS-485. Exar also offers dual / multi-protocol serial transceivers that further help optimize the system architecture by supporting 2 to 8 of the most popular interface standards.

Network Security

The growth of data in the internet is expanding at an astounding rate, being driven in large part by cloud and web-based applications, as well as the growth of mobile devices.  As applications are increasingly migrating into the cloud, the requirement for network security is rapidly increasing.  In addition, the dramatic increase in web traffic is driving the need to optimize network bandwidth.

LED Lighting

 LED Lighting Efficiency, performance, size and reliability are rapidly imposing LEDs as the lighting solution of choice in space constrained portable electronic equipments as well as in architectural and accent lighting fixtures.

System Controls

System Controls Power delivery and control products insures stable and safe operations of electronic systems and power architectures. Voltage references guarantee accurate power generation, system supervisors monitor one or several voltage rails for abnormal operations
