High-Speed Product Test Controllers

The Scout products are high-performance Serial Bus controllers designed specifically for high-speed automated test and characterization applications. Unlike traditional USB to GPIO dongles, Scout products are architected around an FPGA core to minimize execution time and provide deterministic timing.


The SC4415 can be configured for support of MIPI-RFFE V2.1 and/or MIPI-I3C (including legacy I2C).


This device supports manual control using a terminal emulator or software control via it’s API for integration into Automated Test Environments (ATEs). The interface is compatible with any software that supports communication via COM port. The device is verified on Windows, Linux, and iOS systems.


The MIPI RF Front-End interface (MIPI-RFFE), is a dedicated control interface for the RF front end of a device. It enhances the control of the complex device environment, which has rigorous performance requirements, and can include 10 to 20 components such as power amplifiers, antenna tuners, filters, and switches. The interface can be applied to the full range of RF front-end components to simplify product design, configuration, and integration, and to facilitate interoperability of components supplied by different vendors. The conveniences make it easier for manufacturers to address end-user needs for faster data speeds and better call quality, develop scalable solutions, and expedite time to market for new designs in the mobile, automotive and IoT sectors.


MIPI-I3C is a bus interface for connecting sensors to an application processor. It is a core sensor integration technology that can combine multiple sensors from different vendors in a device to streamline integration and provide cost efficiencies. It gives developers unprecedented opportunity to craft innovative designs for any mobile product, from smartphones, to wearables, to automobile safety systems.
