    Addressing the Challenges in High-Volume Production Testing of MIPI-Specification-Based Devices

    The latest trend for semiconductor device manufacturers is to add several high-speed MIPI® specification-based ports to a single device. This enables feature-rich implementations of imaging- and display-intensive applications, although it also poses significant challenges for production test engineers who are tasked with creating high-fault coverage testing solutions on automated test equipment (ATE). Such fault coverage often entails creating a parallel, at-speed, system-oriented functional test while simultaneously grappling with the limitations of legacy ATE and the complexity of the MIPI protocols being tested. This post describes production testing methodologies of MIPI-based devices on any ATE platform, whether it is at the wafer test stage or the final test stage.

    News from MIPI Alliance: New RFFE Version Delivers on 5G Requirements in Timing Precision and Low Latency

    5G uplink and downlink communications demand significantly more radio frequency (RF) bands, and, in turn, the subcarrier spacing (SCS) windows among RF packets are significantly tighter. That translates to unprecedented requirements for tight timing precision and low latency. Development of the MIPI RF Front End Control Interface (MIPI RFFESM) v3.0 has been keenly focused on meeting this challenge and aligning to precisely where evolution of the 3GPP 5G standard has progressed today.

    MIPI A-PHY Featured in Autonomous Vehicle Technology

    Improvements to driver assistance and self-driving systems hinge on collecting and using more data about a car’s surroundings. However, most vehicle networks were not built to support advanced features such as lane-keeping systems and multiple dash displays. As the industry moves toward self-driving and highly automated vehicles, automakers need new interfaces that can support new vehicle connectivity needs.

    Upcoming MIPI RFFE v3.0 Paves Way for 5G

    With its 1000x data traffic capacity-enhancing ability over 4G, the promise of 5G technology is set to herald a whole new era in wireless communications. Beyond delivering a richer and ubiquitous immersive multimedia experience, it is going to transform communication and control for industrial and automotive applications. The self-driving-car revolution is poised to use 5G as its central pillar. With an entirely new class of Internet of Things (IoT) devices using distributed wireless sensing and shared artificial intelligence (AI), it has already started harnessing the power of 5G. The true potential of 5G wireless technology is limited only by one’s imagination. Its scope is truly boundless. And, behind its far-reaching abilities lies the hidden complexities of wireless technology for which the MIPI RF Front End Control Interface (MIPI RFFE℠) specification is a key enabler.
